Stress, Strain and Young’s Modulus – A Level Physics

Published on April 1, 2015 by

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.

      How did you do

  • PearMcMuffin 7 years ago

    what pen are you using?! I must get

    • lowkeylean 6 years ago

      PearMcMuff v sign if im not wrong lol

      It really is pretty cool 😂

    • PearMcMuffin 6 years ago

      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

    • Physics Online 7 years ago

      +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!

    Most useful video of all time thank u so much

  • Ang badang 6 years ago

    Ah… The whole stress and strain intro relating it to students was the funniest/cringiest part of any of your videos xD

    do you need to know how many pascals in a giga pascal?

    • Physics Online 6 years ago

      Iamyou iamyou You should do, yes.

    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

  • kick siva 3 years ago

    Hook’s law = stress/strain but Young’s modulus

  • Ron 3 years ago

    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.

    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

  • Kojo Regenbogen 3 years ago

    >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

    👌♣️🎶 “PASCAL”

  • Binish Babu 2 years ago

    💡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!
