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

93,948
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.

Thanks for watching,

Lewis

      @Becky Donaldson Thanks

  • Fudgey1010 7 years ago

    Thank you for these videos. You’re going to be responsible for my (hopefully good) unit 2 physics grade haha

    • Dimitrios Fotopoulos 2 years ago

      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

      PearMcMuffin
      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?

    • Physics Online 7 years ago

      +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.

    • Perpetual Tom 7 years ago

      +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

    really helpful video!

    Thank you

  • Iamyou iamyou 6 years ago

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

    • Physics Online 6 years ago

      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

    Jezz this is way damn better than my physic prof’s mad lecture

  • Brandon Martinez 4 years ago

    Simple and clear. Thanks!!

  • Onur - 4 years ago

    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.

    amazing 😍😍😍😍😍

    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.

  • Hooman 3 years ago

    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”

  • 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!
