Thanks for watching! Let me know what you’d like to see next in the comments. And don’t forget you can watch the bonus video on Hydraulic Systems over on Nebula - nebula.tv/videos/the-efficient-engineer-understanding-hydraulic-systems.
Thanks once again. A video on how things like pumps, dams, weirs and water treatment plant plant works will be equally great.
Your work is really helping.
I would like to see a never before seen video on enthalpy... Why we always use enthalpy in majority of our thermodynamic calculations and formulas? How enthalpy is different in liquids solids and gases...? Enthalpy is a very very confusing topic in thermodynamics... The formula that Enthalpy = Heat ( Thermal Energy) + PV ( pressure volume product) is actually super confusing for most of us (thermodynamics students) all the teachers have failed to explain this concept especially when this concept is applied in Joule-Thomson Expansion .... Websites , books, teachers and even the Professors say that Joule Thomson effect is an isenthalpic process.. However they really fail to properly and intuitively explain this... the confusion arises form the fact that a sudden compression or a sudden expansion is always refered to as an adiabetic process before one reads the Joule-Thompson Effect ... They say, " Joule Thomson Effect is not isentropic (reversible adiabetic) or adiabetic though there is a sudden expansion; it is an isenthalpic process"
Another confusion arises from the fact that isothermal compression and isothermal expansion is always isenthalpic.... Because as soon as the pressure increases it will dissipate heat and as soon as the pressure decreases it will absorb heat from the surrounding ...
But if we look at the Joule Thomson effect it is not isothermal the temperature drops and most unfortunately what ruins everything is that sometimes temperature increases as a result of sudden expansion 😵 ..... So we still can't apply the adiabetic logic here because according to adiabetic principle gases cool on expansion while gases are also weirdly heating up on expansion.... Why is this so.... ? Can you please explain what happens at the molecular level?
( animations or simulation on microscopic scale )
I would like to see videos on friction (and its applications) and principles of virtual work.
please cover topic of Waves
I request Bearings, Seals, and Valves. Very important to know how those work and how they wear down, and what sort of abuse wears them down quicker. For example an unbalanced rotating mass can damage the bearings.
while most people are out on Friday night i'm here watching these videos. I finally understand mechanical advantage! Thank you!
Amen
@JesusMartinez-zu3xl
You _are_ never done learning, after all!
Hell yea dude save your money and expend the mind, rather than wasting it and decreasing it 💪🏽💯
As a ME student that hasn't taken statics in a while, this was a great refresher!
No I wasn't stop lying
@@johnner8577 "It"
We didn't study gears in statics
this would be covered in dynamics
I am so eternally grateful for this channel. I will become a patron once I graduate and stop being poor.
I am a graduate mechanical engineering I have been preparing for PG entrance exam of Engineering. Believe me!! You will never find this level of animation anywhere.....!! I mean seriously...... classical mechanics with such an perfect examples and articulate animation!!!
May Allah bless you and except your efforts!! Love and Respect from India
Can't agree lesser! This guy is a legend. Btw, i am having the same credentials as you, preparing for higher studies
What exam are you preparing for?
@@reddaxtor5662 Graduate Aptitude Test in Engineering, aka GATE
@@mayurdahiwale5907 all the best to both of you
@Danish_Rasa7
Heh. Based.
Keep at it dude. 👍🏾
Please make more videos, I love them watch all of them! Great work as always
Appreciate it, thank you! Always working on more, it just takes time! 😅
@@TheEfficientEngineer I helps me alot. BTW, Tomorrow, I have applied mechanics exam.
@@TheEfficientEngineer you are doing great work .please make more video on FEM
Stop lying
I'm only here to learn how to hip throw someone thru a window
This is now the best channel that I have watched in TH-cam in terms of explaining engineering concepts and clear animations. I've almost watched all the videos in this channel. Thanks and keep it coming.
One of the best explanations I've ever seen, covering many questions at once
This is by far the most concise explanation of these concepts I have come across. Excellent work, thank you for the information!
These are next-level animations paired with top notch explanations. Thank you for this most excellent refresher and keep up the great work!
Thank you for sharing. The animation is so wonderfully done. It made understanding the subject so much easier. And the logical progression of explaining from lever to pulley to gears is extremely clever and well thought out. This must have required a lot of imagination and fore thought.
This video would've been so useful back in my hs days. The information was delivered in a very easy to understand and digest manner. Great work
You are doing GREAT work these videos have immersuable value for everyone watching them, it is a joy to learn engineering with this kind of quality content to support the classroom, on behalf of every aspiring engineer Thank You
As a mechanical engineering student I really love your videos. I appreciate how you include every minute details in your video. They way you explain the concepts is phenomenal. Only thing that bothers me is the frequency of your videos which come in Months.
I was confused by pulleys and how they work and your video made everything clear to me!
All your videos are gold. It not only bring concept and knowledge, but also develops more interest which is most important thing.
It's been so many year's since I've graduated. Your videos are so helpful to refresh high level conceptual concepts. Thanks
I love watching these videos to refresh my knowledge of mechanical engineering
A gear can also be seen as a wheel of levers where the moment is at the center of the gear and each tooth is it’s own lever. Great video! ❤
That is very true thanks for that.
Yea, I was always imagining them this way too. Imagine that each tooth is a lever with both sides of it equal to each other, but 2nd lever is shorter. And you act with one lever on another.
Informative, concise and simple thank you so much ❤
Love the way you gave the intuition for how energy is the same even if mechanical advantage increased with example of lever
This helped me so much, I am currently studying for technology and when it came to pulleys the teacher’s stuff was so vague and didn’t even explain it. Now I know it so well. 👏🏼👏🏼👏🏼👏🏼👏🏼
Please make a video on surface tension, your videos are easy to understand and less time consuming.
Appreciate your efforts man, good luck!
As a Physics teacher I wish I could buy you guys a pint - These animations are perfect!
Your content is frankly outstanding. Truly outstanding. And i've only given out such high praise a dozen or so times in the 21 years i've existed.
I can't put it differently, your videos are art!
All your videos are really great to watch and are still understable, thank you !
Thank you so much. That was very helpful .
summary of mechanical principles. love it. thank you
Very clear exposition. Thanks.
Every time you post a video, I get so excited. Your videos are excellent. Thank you!
Every time I see a notification of your channel, I smile. I think I'm in love.
Me to
Brilliant! Please do more videos, you are very professional. Thank you!! Will recommend to friends
Please make more frequently videos , learnt so much from all of them ,
Love from India 🙏❤️❤️💙
this is exactly what I wanted to watch!!! surely an educational advantage your videos are😇
Your explanation is 1000 times better than my physics teacher! Good luck
😂😂😂
After watching this video I suggest to take also a look to the Chevrolet videos about spinning levers and differential and the circle is finally complete!
Please 🙏 post regularly, your video's are dope!
I absolutely love this! The animations are super helpful and allow me to wrap my head around the concepts much more efficiently. I can be a little slow sometimes, so your work is much appreciated 😁👍 I just subscribed and look forward to learning more about my favorite subject. Thanks for sharing your creativity, ability to teach, and overall mad skillzz with the world!
No you didn't your lying
@@johnner8577 *you're
Very interesting. I like that you explained clearly and allowed time to think and consider between each explanation.
Thanks, I realise I was really missing some common knowledge on this.
I more or less understand how lever action worked even if I didn't know how the math worked out but I didn't understand the other 2.
As always, excellent for interview / viva preparation!
excellent tutorial to introduce the concepts
I love how gears amp up speed in a given period of time. They're the reason I fell in love with cycling 😄
It's a great video
Since you asked... Optimizing efficiency in an electric motor power drive would be a nice addition. What are the tradeoffs for using flywheels to store energy? Heat loss minimization? Your approach to pulleys, fulcrums, and gears is great.
I just purchased a subscription at nebula. wish there was a way to give you credit. I watched the hydraulic video and followed. I'm a beginner machine mechanic at a plant so the way you layer out theses videos was perfect.
Amazing video! Must take alot of time to develop, keep up the hard work !
I LOVE THE WAY THIS VIDEO IS DESCRIBED AS IT IS SHOWN IN TGIS COLORFUL EASY TO UNDERSTAND ANIMATION. THANKS . HAPPY NEW YEAR.
Good 👍 really helped me for my research for our bridge mechanism
I'd like to see a video on sizing pneumatic rams, and how to work out the best place to position them, and the forces involved.
damn, i didint think i would learn some applicable information here. nice, that rope levering system makes total sense now.
Amazing video
Thank you for making feel less stupid. I never understood when my lecturer tried to explain it. But now it's clear to me.
Most Excellent Video. Thank you very much!!
Great work as always. Thanks so much.
Everything in your videos is perfect 💯
Beautiful presentation
I'm an EE. Im fascinated by mechanical systems but dont know much about the details. A lot of this stuff is somehow very intuitive, but the reasons why it works seems like magic. Your explanations of the reasons why it works are excellent and easy to understand. Subscribed. Looking forward to more videos! Also i keep noticing how almost all mechanical systems have electrical equivalents with similar equations. The hook's law spring with a mass differential equations are very similar to capacitor and inductor differential equations for example. Gears are similar to electrical transformers. Pulleys and levers are like electrical amplifiers. Its pretty neat how that works out.
Nice subscription list. Proud of you as a Ukrainian fellow
@The Efficient Engineer
please consider making a course for using blender for education content. I know there is a lot of blender courses and videos, but you are directing the software strength in a very specific way that is not mentions among the other videos.
