I don't really know how to thank you , you have no idea how important are you for students , you seriously contribute to a lot of my top grades , THANK YOUUUU
I’m just a kid who wants learn more, but I didn’t know where to start so I decided that TH-cam could be a good source of knowledge and after seeing this video, I think I made a good decision.
You had helped me a lot like A LOT, i have been watching your videos to help me with exams, and yesterday when my teacher played one of your videos in class, i was like 😮😮😱 Now the class know how helpful you are, thank you
strongly agreed, listended to prof bullshiting for like two hours doesn't understand a thing about material what so ever. Hop into youtube,20 mins later, Imma the mf king of the class!!!LOL!!!!
You know everything.. You are the man!!. Now I am trying to get videos on solid and structural mechanics but am struggling to know which video of yours should I start with.
Can we say that the Young Modulus is the amount of force needed to stretch 1m^2 of a material to twice its size? Because if A = 1m^2 and deltaL = L0 (meaning that the material has got to twice its original size), then F = E. If the material stays in the proportional limit during the stretch, I think this is safe to say. What do you guys think?
Good evening I have a question what is tge meaning of Re Because se gad a question involving that but have no idea about that. This the question:assignment Suppose that the effort in a tie rod is 89.20x104N when the load to be lifted dis maximum. The tie rod is a still cable with elastic limit"" Re=580N/m2 "" and its young modulus E=2x104N/m2 . Consider a safety coefficient of 0.25 and a length of 3m Determine the section S and the diameter D of the cable such that the tie rod can resist safely. NB. Diameter available in the market in mm 50-60-80- 85-90-95-100-105-110-115-120-125-130-135-140-145-150-155- 160-165-170-175-180 What then will be the change in length of the cable?
I have a problem, I would calculate the movement about a plastic lever. For example a plastic snap hook. I know the formula that Y = c * (E * (L * L)/H) where y is the movement, c is a constant (physical form about the lever), E is the secant modulus (stress/strain), L is the lenght of the hook, H is the thickness of the hook The main problem is finding E in the material datasheet! Because inside them you find Yield Stress in MPa and Yield Strain in %. Stress at break in MPa and Strain at break in %. So I can't calculate E with these datas
AB(elastic deformation) and CD(plastic deformation) plastic deformation means the material can not get to original position upon removal of applied load it will may fracture if the applied load goes on increasing
I need to see all this applied to an actual problem, otherwise I'm still clueless. And everything is hard to begin with anyway if you're Laurel and Hardy rolled into one [imagine being that way for 58 years now].
Hi. I have a doubt in Hooke's law. It States that within elastic limit stress is directly proportional to strain. But within elastic limit there is no strain BCOS there is no change in dimensions. Then how we will calculate modulus of elasticity?
There are changes in dimensions and hence there is strain within the elastic limit, but due to the object being in the elastic region, the deformation (change in shape) is not permanent, but does exist as long as the force (load) is applied. Elastic limit is the highest stress a material can withstand before permanent deformation, it's not the only time strain is present. This therefore allows you to calculate the elastic modulus. Hope this makes sense and you find this useful : )

I've started watching your videos after my mechanics class and I gotta say you make it so much clearer than my teacher.
Absolutely true😩🫰
You're a treasure. You have no idea how much you're saving the education system worldwide
No problem any day
The true saitama, a hero that doesn’t need recognition
I don't really know how to thank you , you have no idea how important are you for students , you seriously contribute to a lot of my top grades , THANK YOUUUU

Did it work?
Yeah. Me too.
When he mentions Area. He is referring to the cross sectional area of the material.
The best teacher ever existed. Thank you, Sir.
Maybe this is the first time for me to understand something in physics this easy

This is one of the best videos i have seen on youtube explaining these concepts.
Any other ones?
Bro, I was able to complete my course outline topics a week before exam because of you. Thank you.
JG...seriously THANK YOU. I really appreciate your channel. This content has been invaluable to my undergraduate career. Again, Thank you ^_^
thanks ! i will sit for my final exam in less than 3 hrs . this is very helpful
You had helped me a lot like A LOT, i have been watching your videos to help me with exams, and yesterday when my teacher played one of your videos in class, i was like 😮😮😱
Now the class know how helpful you are, thank you
Sometimes I wonder if he's Shawn Mendes
😂😂Word
😂😂😂😂bruh
Why? Does he moonlight as a mediocre singer?
you are the lifesaver of chemical engineering students!
HI FELLOW CHEM ENG IM DYING SEND HELP SOS
This person makes me understand better than my physics teacher
I feel you
Thank you I passed my exams thanks to you. ❤
This man is going to be responsible for my engineering degree I will be getting in 2 years.
strongly agreed, listended to prof bullshiting for like two hours doesn't understand a thing about material what so ever. Hop into youtube,20 mins later, Imma the mf king of the class!!!LOL!!!!
lolol same in 6 years (hopefully if I end up doing it at uni lol)
Done now?
@@footballclips5013 LMAO. I will be in 2 months!!!!
What about now are you done
bro these vids are saving my life
A teacher indeed , I am your greatest fan
Using these vid to prepare for my final exam before university :)
Final exam from 30% percent is tomorrow 4 chapters and you are saving my ass man thanks.
This guy just explained everything in 20 mins which my teacher could not do in 2 hours
I really wish you was my teacher 😢. Ive been watching his videos for the last year and thank god his videos have helped me a lot
i dont know if i would do well in school without this
I really don't know how but I found everything I'm studying at the college until now here in this channel 😂❤
Am i the only one wondering how this amazing teacher looks like behind this screen? 🙆♀️
You know everything.. You are the man!!. Now I am trying to get videos on solid and structural mechanics but am struggling to know which video of yours should I start with.
ما شاء الله، شرح رائع 🔥.

Best channel on youtube
I will share my testimony when I see my first semester results
how's your result
how is your result?
How were your results??
How's your result
did you fail?
You are a genius👏 thank you so much for your videos they have helped me a lot
Thank you sir.❤
Your lessons have helped me so much.❤
Be blessed.
Thanks for saving my life, thanks soooo much!
my whole grade depends on your lessons, thank you so much!!
you are actually a bad person
@@ranendrasen7956 LMAO WHY
@Arzounawaz virk yeah!
I appreciate you my friend
how does he know so much ? i watch all his videos for most of my modules
amaan rampath i want to know the answer too, he has a degrees in everything
Any undergrad in college who majored in Biochemistry pretty much covers all of the topics that are on his channel.
thank you, my teacher cant teach to save his life so im relying on you lmao
We need a face reveal
organic chem tutor is not a real person...
hahaha maybe he is somebody form another planet!! hahaha maybe alien
Or maybe just your regular brainiac
@@amaanrampath4100 what???? what is he then
@@정유나-q7y A robot, duhhh
He deserves more.
Listing to that helped me to write a good lab report thank you so much.
This video tutorial is dopeless i understand a lot now thanks A LOT
This man is GOATED ❤️
You should get more views
I always knew stress and strain were involved in physics, lol. I love Physics XD

I now fully understand the purpose of the Young's Modulus after 15 years later since graduating college.
Thank you sir you are saving my life

Thank you
Good evening
I have a question what is tge meaning of Re
Because se gad a question involving that but have no idea about that.
This the question:assignment
Suppose that the effort in a tie rod is 89.20x104N when
the load to be lifted dis maximum. The tie rod is a still
cable with elastic limit"" Re=580N/m2 "" and its young
modulus E=2x104N/m2
. Consider a safety coefficient of
0.25 and a length of 3m
Determine the section S and the diameter D of the
cable such that the tie rod can resist safely.
NB. Diameter available in the market in mm 50-60-80-
85-90-95-100-105-110-115-120-125-130-135-140-145-150-155-
160-165-170-175-180
What then will be the change in length of the cable?
15:01
Is the F directly proportional to the E??????
doing a great job JG your tutorials are wonderful.
Yo dude you've helped me alot
It's a great explanation
What would I do without u 😩😩😩😩🥺🥺🥺🥺
You’re such a W mans
Thank you 💓😊
Set the speed at 2× and you're good to go ... saving time :)

Strength of materials
Thanks u so much my sir is bad ur good
its NOT awkward that he greets us
This is a great video thanks!
at 1:20 you wrote hookes law as f=---kx why is k negative?
you should watch simple harmonic motion video he explained it there
He ain't Gona reply to you stup1d b1tch

thanks , mark wahlberg
Does the thickness effect on the stech or compres efort
what is formula of elastic limit? Is it same as youngs modulus Y?
Between C and D does that mean the object has deformed or can it deform in AB as well?
AB(elastic deformation) and CD(plastic deformation) plastic deformation means the material can not get to original position upon removal of applied load it will may fracture if the applied load goes on increasing
If wood is stretched wont it break 😕
I need to see all this applied to an actual problem, otherwise I'm still clueless. And everything is hard to begin with anyway if you're Laurel and Hardy rolled into one [imagine being that way for 58 years now].

I'm watching this for my college class on conceptual physics... I'm even more confused... but thanks?
Seems like a you problem
How are you confused?
I love u sir😐😐
Deformable solids is a fancy way of saying poop class.
Very helpful
Thanks a lot it was very helpful
I need when stress is propersional to strain how they can be change easy way
Thanks.
Can you solve questions on the lessons you give😢
THANKS
Thanks for channel
