When revising for your exams it may seem like you are under stress and strain, however, they are quite different but they do allow to investigate materials. Their ratio can also be calculated giving the Young's, or Engineering, modulus.
Thanks for watching,

Great video! Thanks! 😀 Keep up the good work :)))
@Becky Donaldson Thanks
Thank you for these videos. You’re going to be responsible for my (hopefully good) unit 2 physics grade haha
How did you do
what pen are you using?! I must get
PearMcMuff v sign if im not wrong lol
PearMcMuffin
It really is pretty cool 😂
Tanya Y I’ve had two of these pens since this video😂
Your’re awesome man! Good job i’ve found you, doing a practical on Hookes Law tomorrow where we have to use micrometres to find the cross sectional area of wire then apply a force to it. What more can you tell me?
+Perpetual Tom Thanks
+A Level Physics Online This is a straightforward practical – make sure the wire is clamped firmly, it isn’t kinked when you start and also that you wear safety goggles – if it snaps the end of the broken wire can flick into your eyes.
+A Level Physics Online OK thank you very much!
life saver
Most useful video of all time thank u so much
Ah… The whole stress and strain intro relating it to students was the funniest/cringiest part of any of your videos xD
really helpful video!
Thank you
do you need to know how many pascals in a giga pascal?
Iamyou iamyou You should do, yes.

Thank you very much for your honourable and altruistic work. Your videos are immensely helpful for me to understand the profound philisophical significance of physics.
Why do you sound like Gordon Ramsey? Lol
u r good
thanks a lot!
fik me hrd
Jezz this is way damn better than my physic prof’s mad lecture
Simple and clear. Thanks!!
how can i find E(elastic modulus ) from psi
Hook’s law = stress/strain but Young’s modulus
I don’t like it when people make their Xs like that! It looks sort of like a half-assed, infinity symbol or lower case alpha and nothing like an X. When you’re looking through hand written calculation, from different people, clarity is a God send.
Good video though, clean and thorough.
Thank you very much for this useful video
amazing 😍😍😍😍😍
good video!
Thank you
best simple explanation
1:30 i blinked i thought my brain shut down for a minute and i didn’t realize. i had to rewind the video lmao
>210 gigapascals
_YagaKimi intensifies_
I tried making the joke work, but this Young man’s modulus is too big for my hole joke.
N/m2 is not negative, you put a negative mark before the square 2
great teacher is that wtf they are saying it is hard ohhhh you make it easy teacher you did it
Something more would have been better sir
👌♣️🎶 “PASCAL”
💡Coiled springs appeared early in the 15th century,in door locks. The first spring powered-clocks appeared in that century and evolved into the first large watches by the 16th century.
In 1676 British physicist Robert Hooke postulated Hooke’s law, which states that the force a spring exerts is proportional to its extension.
Very useful video, easy and understandable, thanks!
