Stress and strain is one of the first things you will cover in engineering. It is the most fundamental part of material science and it's important you understand some of these ideas going forward.

The second channel fell through. I need a university to sponsor that channel and provide the course materials, I was hoping to just do the animation and narration. Still hopeful it will happen further down the line, but for now I just don't have enough time.
Real Engineering Did you consider Pluralsight for providing more in depth courses? I love it, professional and viewer friendly material with monetary compensation baked in. No university required, I hope. :)
Maybe get some friends to work on the second channel.
Awww... as an overly bored seventh grader that would be amazing.
Hi
İndustries are not responsible for implementing sustainable practies.
Embodied energy of a material/object is a fundamental index of impact on the sustainability.
Are these T or F?
Please don't give up on a more technical channel. I am a starting my third year of mechanical engineering and I very much value your content.
15 videos and 187k subscribers? Efficiency level: engineer
his other acc has 0 videos and 15 k subscribers
Hey, martis, what is that icon from? I see it everywere!

Absolute perfection
Sounds like a business channel.
Wow, you've just summarized my 60 hour material science course in 6 minutes lol.
Nelson De Vera I agree
lol.
This is why the internet is a miracle
We only spent like 5 hours on this lol, but the video is very clear and well done
thats college for you
As a Materials Engineer I can confirm the information in this video is correct and a great introduction into materials.
What's harder, Material Engineering or Electrical Engineering ?
Sunny shah hahahahaa EE is the hardest by far
@@BangMaster96 Material, as all fundamental engineering is based on the Materials you can use.
@@BangMaster96 I'd say electrical but that's pretty hard to determine. It mostly depends on who's learning it I'd say. I'm studying material engineering btw.
@@Max-pn8dk anything electricity related is just fucking annoying. I hate it so much i avoided it like the plague during my formative years as a chemical-technical lab assistant.
I've been in the trades my whole life. Tool & Die, Model Maker, Welding, and sheet metal fabricator. I got a degree in Mechanical Engineering while working nights, and I enjoy your series a great deal. It's easy to forget that engineering touches everything we use in our daily lives. Your series makes is easy to understand and appreciate what goes into these products.
This video is super fast, hopefully you got a basic idea of material properties. I wanted to create a second channel where I can explain things slowly and in detail for the people who want that kind of content. I am hoping to partner with a university and release proper college grade education on that channel. The link is in the description. Thanks guys. Really appreciate your support. Back to normal videos soon! Hoping to do a Q&A at the end of the year, so go ahead and follow me on twitter if you have an questions you would like to ask. twitter.com/Fiosracht
Hi, I thought ductile meant can be drawn out into a thin wire? :-)
That's an excellent idea ! You should contact the guys in CrashCourse, I'm sure they would be interested in patronizing you as well.
well a non-ductile material certainly can't be drawn into a wire. Ductile just means the material deforms significantly before failing. The opposite of that is brittle, where the material shatters suddenly.
Real Engineering ahhh thanks
Real Engineering man i understand english well but as a 13 years german dict.cc I'm coming xD
It's pretty insane how much you've grown by just a few really high quality videos. So happy that it's going well for you, I hope that you keep growing so you can do this full time without having to think about economy.
I retired a few years ago as a physical metallurgist. This video is well made. Thank you. "Youngs Modulus", brought back a lot of memories.
As an Mech/aerospace guy I can def say a lotta material scientists/metallurgists really like playin around in the lab haha this is what I observed when I was taking my mechanics of materials course lab they were putting all sorts of stuff in the utm needless to say the lab tech was mad😂
As a mechanical engineer, I find that your videos are excellently presented. They cater to those without much background in the subject while not insulting the viewer's intelligence. Well done. It would be great to see your videos in classrooms.
I didn't have a good professor for my Strength of Materials class, and this 6 min video taught me more than his class did in 4 months. More videos on the concepts for material properties would be amazing! Specifically Mohr's Circle and its uses.
My first 3 weeks of material engineering class in 6ish minutes. Such nice work. Thank you.
I love your channel so much. I admire instead of saying "Oh this works because it has this," you explain how it works and the math behind it. I love having a greater grasp on the world and your channel is perfect for that.
Wow. I feel like you were able to perfectly explain in 6 minutes what my professor could not these last few months. I've been surviving this course on thoughts and prayers alone.
I am just a guy who likes to spend his free time on TH-cam, dicking around watching videos over space exploration and a few outlandish scientific concepts. I already have a hard time figuring out what to do with my life, and I'm currently doing an exchange year in Germany wondering what to study in college(or even study straight away at all ).
Finding your videos in my reccommeded list has really sparked an intrest for me in material science, a branch of science I've never really bothered to think to much about before, yet also made it clear to me that I would live to study some form of physics. It's so hard to be in a classroom thinking about when the subject material will be relevant, or staring at marvels of the world without understanding what intellectual work went into it (let alone understanding the work in the first place). So, thank you. And please, after watching your latest video on the power grid, keep up the good work
I've regained all the forgotten topics within 6 minutes, every single second some good hint and reminded me the beginning of the materials lesson. Thanks a lot. keep on going mate. These type of videos are absolutely useful.
Trust me on this m8, 1 channel is probably the better way to go, just less clutter(aka not needing to worry about not having uploaded a video to one or the other channel in a while), and the youtube algorithms like it more when you upload more videos on a single channel
The second channel will be seldom used for now. It's purely for videos with lower production value and more technical content. I want to keep this channel for really high quality fun videos.
Ah I understand what you mean, btw you've got a nice growth curve going on youtube :p gratz
I hope it wont be inactive for long, I really enjoyed this and would love to see more.
This should really be called "Mechanical Properties". Materials have all kinds of other properties such as thermal, electrical, optical etc.
And all of those were termed networks IBM long before encryption method and the business had you back two play mirror mirror n the spoils,owe dear matter as say,objected old chap,goose March next.
Nathan Soper NO, "Physical Properties", which is a sub speciality of metallurgy.
I agree Nathan
I'm not complaining.
Biggest confusion in material science about stress-strain related stuffs, is that whether it should be considered under "mechanical" properties or not. In reality it's basic to thermal, electrical, magnetic, optical and acoustic properties as well. Because the nature of external force can be anything. eg. electric potential difference/voltage applied on the material can also cause strain and thus stress, which are actually internal reaction forces to the external action forces.
Ironically, internal reaction of a material, ie the stress is fundamentally of electromagnetic type.
This was really helpful for my material science class. Would still really love to see more videos like this one day.
Moin, I'm from Germany and some of your videos are already used in technology lessons. Your videos are really good. Please don't stop making videos. And thank you for finally putting the music in the description ^^
This video was truly amazing!!! Gives you a core understanding of material behavior related to the loads applied.
Thanks a lot for this kind of videos. I am an engineering student, i use to visit your channel to watch tanks and aircrafts. Now i can watch your videos to pass exams. Thanks a lot for helping me by compressing hunderds of book pages to several enjoyable videos.
Beautiful... Can't wait to see some of the videos on your other channel. Depth is always a good thing in my opinion, especially with concepts this valuable.
As a Metrologist who works with all of this every day, I just had to watch it. You did a great job
The fact about the ships and Katana construction were super interesting! I love the real world examples in conjunction with the facts - thank you!
Glad to found this from your channel. Planning to take material science and engineering master on next year. Right now just gather the knowledge needed. Thanks, love from Malaysia
Excellent video, so concise! I did some work for my FYP of my bachelor's degree using tensile tensing. If only I had found this video back then, would have saved me a lot of effort trying to comprehend it 😅
I teach Design and Engineering at high school. This has to be the best explanation I have ever come across. It will be so helpful to my students.
I'm graduating with a degree in Civil Engineering in May and this is the best explanation of basic material properties of seen. Well done.
I'm a 3rd year engineering student in the Philippines I recently found this channel and the videos here can help me prepare for my majors
I had to watch it thrice to get all concepts right, but I think this is going to help a lot when I have material resistance class two years from now. Thanks a lot
Incredibly well explained! I'm an engineering student and I'm sure that that there is no need to be doing such studies to understand what you explained, well done!
Thank you a lot from Yildiz Technical University, Istanbul. Your videos are helping me with my Material Science class.
Rockwell hardness test
1.Minor load is applied to the material by an indenter (zero point).
2.Major load is then added which indents the material.
3.Major load is removed maintaining the intial load.
I REALLY liked the video, but it left me wanting even more! About how exactly can materials be tailored to fit specific criteria of hardness, ductility, etc. I didn't even imagine that about a katana, or any sword for that matter. Great video!
I'll be covering steel and it's ability to be hardened in detail soon.
Real Engineering great!
I'd like to see that, I'm making some mixing blades from steel rod and could use some insight fine tuning them. Soon?
Waiting for content on your second channel. Many thanks for your time and effort on making these videos.
This video is a treat to the eyes of a civil or mechanical engineer. Thank you so much.
I'd Love if you did a series of videos on all the engineering advances in the Concorde, i feel like it could be a pretty good series with all the technology onboard Concorde and your video production quality.
Either way, Another quality video.
I learned more in this video than I did in a semester taking that materials class.
I remember watching this in my first semester of sophomore year in high school knowing it would be relevant to my future schooling and now I’m a junior material science engineer and have to perform tests and make stress strain curves from load and extensometer data
I've started taking a course in A-level physics which has a unit on material properties, this is going to be REALLY helpful!
This video is a fantastic overview of the terms used in material design. Thanks :)
This is awesome. You just summed up 10 hours (1 month) of my materials class into less than 6 minutes. I hope you keep these up!
10 hours a month?
Two one and a half hour lectures / week
StealthPlatypus1 cool cool.
never saw such a smooth e-module curve before :D
never the less... another great video
An excellent tutorial
I wish there were more like this. (edit one of the best I've seen in 10+ years on yt)
Subbed/liked no hesitation.
Pretty good video! I like it! If only you'd uploaded this before my exam in material science!
hey im a leaving cert enginnering student and i had a test envoling exam papers one of the questions involved age hardening and at first i didnt know what it was until i rememeberd it from your aluminium video, thanks so much for your great content and production and animation quality. Keep up the good work.
Fantastic. That makes me happy.
Love this movie!
Please make more technical videos like this🙏🏼
Reminds me of the good old mechanics lectures..
I used to test plastics for landfills, and even later I worked in jewelry you could see how gold is malleable but ceramic wedding rings were extremely hard and couldn't be worked like gold - and the sapphire crystal glass used on high end watched were superior in scratch resistance. Oh yeah, and diamonds are in there too as hard (scratch resistance) but could be chipped (toughness) - really awesome video here.
Very pumped for even more Real Engineering content! :D
Thanks Inés!
@@RealEngineering THE UNIVERSAL, SIMPLE, CLEAR, AND TOP DOWN MATHEMATICAL PROOF THAT E=MC2 IS F=MA (ON BALANCE):
It is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience.
TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity.
E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy.
Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity.
NOW, carefully consider what is THE MAN who is standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=MC2 IS F=ma. Very carefully consider what is BALANCED BODILY/VISUAL EXPERIENCE. (LOOK up at what is the blue sky, AS THE EARTH is ALSO BLUE.) Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. Great. It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. E=MC2 IS CLEARLY F=ma ON BALANCE. Objects AND MEN fall at the SAME RATE (neglecting air resistance, of course), AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The rotation of WHAT IS THE MOON matches it's revolution, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Consider what is THE EYE. So, LOOK at what is the fully illuminated (and setting) Moon AND the orange Sun ON BALANCE. Now, think about what is LAVA. E=MC2 IS F=ma. SO, we then multiply ONE HALF times one half in order to determine the size of the Moon. (It IS about one fourth the size of the Earth.) This is CONSISTENT with the fact that the Moon IS (on balance) LAND. Therefore, the density of THE SUN is (ON BALANCE) about ONE FOURTH of that of what is THE EARTH; AS E=MC2 IS then CLEARLY proven to be F=ma; AS ELECTROMAGNETISM/energy is gravity. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Again, it all CLEARLY makes perfect sense ON BALANCE !!!
The BULK DENSITY of the Moon is comparable to that of (volcanic) basaltic LAVAS on the Earth. The energy density of LAVA IS about THREE TIMES that of water. SO, now, get a good and CLEAR LOOK at what is the ORANGE SUN !!! We WOULD then multiply ONE THIRD times one half in order to obtain the surface gravity that is experienced by the man on the Moon. (It IS one sixth of that of the man who is on the Earth.) The maria ("lunar seas") on the Moon do take up ONE THIRD of what is the near side of the Moon. Excellent. The Moon is ALSO BLUE on balance. Great !!! Now, in conclusion, the land surface area of THE EARTH is 29 PERCENT; AND this is EXACTLY ON BALANCE WITH BOTH one third AND one fourth; AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS CLEARLY AND NECESSARILY F=ma !!!!! GOT IT !!! GREAT.
E=MC2 IS CLEARLY F=ma ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY proven to be gravity ON BALANCE. Gravity IS ELECTROMAGNETISM/energy. It must be, and it is.

Thank you so much for your educational videos. As a aspiring engineer these videos really help.
:)
I spent 2 weeks of High school Engineering learning about this and you just explained it in 5 min
Tensile test:
stress-strain curve
yield strength - elastic deformation
ultimate strength - plastic deformation, necking
Young's modulus/ elastic modulus (how stiff the material is)
safety factor
stiff (high carbon steel)
flexible (rubber band)
tough (the material absorb a lot of energy without breaking)
ductile (deform under pressure)
brittle (glass, ceramics, cast iron, the material break with very little deformation)
hardness (is a measure of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied, directly related to the stiffness and yield strength of the material, rockwell hardness test)
So cool, I learned this in my first college year but now I understand it even better !
Another good way to think about toughness is that its units are the units of stress*strain, which is Nm/m^3, or alternatively, the energy stored per volume
great work, simple and straightforward explanations
I really like this channel, you have a fantastic voice for youtube.
This is one of my subjects for a test I'm having tomorrow , very nice explained
those wordsa are:
stiff
strong
ductule
brittle
tough
hard
right?
ductile, but yes, these are it.
ductule
I'll rewatch this video when I take strength of materials in the fall semester. Another great vid.
I get the desire to keep the high production videos separate to these (this video was great, by the way) but to be blunt, and not write a few paragraphs of my opinion/reasoning, I'm not sure your channel is large enough yet to already consider splitting up content on a different channel. Even huge TH-camrs lose views on secondary channels.
I understand the potential partnership w/ a university may call for it, but if it ends up being just a personal choice, my vote it to keep them here and maybe just label these types of videos differently (maybe a short [tag] in title or a slightly different thumbnail theme).
Obviously, at the end of the day, you know your situation best. Good luck with getting that partnership, I know everyone who likes your main content will gladly watch proper college grade videos.
As someone who is also stuck on what to do with separate series on a channel, I find these comments very insightful. :) I am very sure +Real Engineering can pull it off either way (and especially if he can partner with a Uni, I think a separate sponsored channel is definitely the way to go) - but I'm sure an informative title tag would work too
Yeah I wouldn’t want to be bothered to be checking two channels tbh
I thought the Titanic's problem was the forward part of the hull that smashed with the iceberg was held together by wrought-iron rivets instead of the regular steel rivets (because the machinery for automated riveting was too wide to fit into the narrower area there); the simulated collision calculated that the wrought-iron rivets just didn't have enough tensile strength to withstand the pressure.
I am in love with this channel need more about properties of Ti aL AND STEEL .. AND COMPARISON @Real Engineering
Thank you for the informative and short video, Is there any sequence that we can follow for learning about materials properties more?
I thought I was procrastination but these videos will actually help with my materials exam next week.
Yes please! I'll be taking mechatronic engineering in the coming years and all I get for any TH-cam educational videos are repeated "these are the basics of what it is, now join our university!". I know what it is but is like to educate myself beforehand lol. You seem like you took mechanical and/or aerospace engineering but still it helps since mechatronic covers such a huge range. Hell maybe you can check out other engineering branches like bioengineering some time.
I really like the content here. Maybe now TH-cam will see a growth on proper engineering videos like it did with physics videos. Maybe how another person to help make more videos?
Joshua W im starting electrical and mechanical this year :)
Interesting! Currently studying Vehicle engineering and is half-way through the solid mechanics course.
Dope! Can't wait to see more stuff like this!
Bless me guys, I’m going to learn material science next day for the very first time😭
Amazing video....job well done....Do keep uploading further ones
this is the best ebgineering channel on youtube, fact
Great content, good illustrations and to the point.
I'm guessing you're going to get a huge surge of subscribers from the MinutePhysics collaboration.
Hi, I'm one of them. I watched a handful of your videos to make sure I'd be interested (hence this comment being on this video, not the collab one), they were all great. Looking forward to more, keep up the good work, all that kind of stuff.
Thanks bud!
USEFUL ENGINEERING, MUCH NEEDED IN PRODUCT DEVELOPMENT!
i cannot express how thankful i am for this video
Im German and I was in Ireland (Kilkenny) on a student exchange and I love your Irish accent! Since the exchange it's my favorite accent (the one most natural to me)
This video was linked in my Aircraft material PDF file, from my school! I guess congrats!
I've watched this video probably 2 or 4 times since it was released. But I still have to come back to it every so often because I keep forgetting what the different material properties are and what they mean. I guess it's one of those things where I don't use it a lot day to day, so I just naturally forget it over time. Like how I had to teach myself long division about 6 times before I finally stopped forgetting. Because who long divides these days? I only needed to use it because I set myself the task of finding a square root of a number by hand. Otherwise I wouldn't have even needed it. Nor have I since, that I can recall.
This is going to be an AWESOME channel!!!! (current Mech.e student)
my science fair project was originally inspired by watching this video a few years ago, and i impressed a few professors at the USNA for knowing all this info
Awesome video, was always curious about this topic.
I'm studying Materials Science and Engineering, in fact I have an Exam about Mechanical Properties next Week.So I'm excited looking forward for your next Videos in this Topic!
Thank you for making those videos.
I wish they had this when I was an engineering student....awsome video
I remembered my Material Science lesson, thanks for video :)
This is what I do everyday. We call the the tensile, yield and elongation test basic 3. We also perform Rockwell Hardness Testing , grain structure and customer specified heat treatment.
You deserve the sponsor. Keep up the good work!
I love how much you have grown. Been here since the early days. just one thing. Your mic can be better :)
This video was recorded between Ireland and Dubai. Audio quality is all over the place. May invest in a nicer mic soon, but the blue snowball is nice.
From what I've heard the blue snowball sounds better so it could be in the settings? Nevertheless I was nitpicking.
Thank you..explained properly but I think in the tests we can issue precautionary warning against irreversible nature of scratch or indentation
Also I think we can restrict and prohibit few material indentations
You should clarify that the proper way to measure Young's Modulus is by V^2*d=E (with v, velocity of sound in the material, d the density and E, Young's Modulus), because, although it gives us an approximate value, it's not the real.
On the other hand, when you talk about tenacity, is the surface below the curve, but excluding the elastic energy (that recovers): so, it should be the total area minus the area below the line (with the slope E).
Pretty good video, though. +1
Very informative.Thank you for sharing this video.
thank you!!! I have a class in this next semester.
Thanks for the fantastic resources!
I wish you made more of theses basics of engineering videos
The side scrolling text in the beginning of the video. This is why we need at least 60 fps video. Otherwise it is a slideshow.
Just want to comment that this video is linked in a keynote of Stratasys, a large Additive manufacturing company. Another assurance to the quality of the work you do.
You came close to defining an additional property-- RESILIANCE. Resiliance is analogous to Toughness, in that it is quantified by the area underneath the stress-strain curve. But the area is measured from strain=0 to the Yield Strain (which occurs at the Yield Stress.) whereas Toughness measures area all the way to the Ultimate Tensile Strain (breaking point.)
The physical characteristic of Resisiance is that it quantifies the amount of energy a material can absorb and still return to its undeformed shape. For a plate, for example, this would be dent resistance. In general, it's a measure of springiness. This differs from Toughness in that Toughness quantifies the energy absorbed (converted to heat and deformation) to rip the material in two.
Yes dear,but that's a cycled primary which means there's not ever been anyone but you too need too repeat such useless total nonsence too point some matter words out like that why it's usually spring time for hotler?
Steve Bez I can't understand your comment. Can you explain your point to someone who speaks English better than you, and have them write it instead?
Please upload more videos like it....great work
Super interesting video. Nice work. :-)

hey, I showed your monopoly video to my family! love your channel, I'm subscribed.

@@BirdRaiserE Einstein never nearly understood TIME, E=MC2, F=ma, gravity, or ELECTROMAGNETISM/energy.

I did stuff like this in the first semester of mechanical engineering in Athens, of course in a more detail but still ... nice
