Ductile and Brittle Materials – A Level Physics

46,288
Published on April 2, 2015 by

A short video that explain the various material properties you need to understand and identify from a stress-strain graph. From brittle substances like glass and a Crunchie to the plastic deformation of copper and a Mars bar.

Thanks for watching,

Lewis

    Hey these videos are very helpful! I was wondering whether you are planning to do any electricity videos? 

    • Physics Online 8 years ago

      @Syed Ahmed I am planning to, I’ve just not had time yet, they will be on here soon.

  • Hyde 7 years ago

    Excellent video! Any plans on doing A2? All these videos are from AS level. Thanks again. Looking forward to it.

  • pinkheart91 7 years ago

    Hi, can you please make playlists for AS and A2?

  • Amitesh Nagarkar 7 years ago

    Just discovered this channel, have learned and UNDERSTANDed so many concepts so far – its only been 20 mins. OCR A 2015 Physics is hopefully not going to cause me problems, as long as you are here! Thank you!

    • Physics Online 7 years ago

      +Amitesh Nagarkar Glad to hear it! Hope it all goes well for you.

  • Guy Riese 7 years ago

    This is the best way of teaching Ductile and Brittle Materials I’ve ever seen – awesome vid!

    • Physics Online 7 years ago

      +Guy Riese Thanks. I find it’s hard to imagine metals as ductile since in everyday life they seem so hard. But everyone knows about sweets.

    Would it be possible for you to do an online revision session the weekend before our depth/breadth exam? perhaps for an hour or so. I think there are a few websites where you can stream you computer while allowing us in the chat to ask questions. That would amazing last minute revision!

    • Physics Online 6 years ago

      I couldn’t get it to work last time – I’ll have another look this evening.

    • Callum Atwal 6 years ago

      I can help if you like, I’ve done some live streaming before

    • Physics Online 6 years ago

      Email me at contact@alevelphysicsonline.com with a few more details.

    • Ang badang 6 years ago

      This needs to happen.

    • F1rools22 5 years ago

      A Level Physics Online did this ever happen?

  • Zoraiz Qureshi 6 years ago

    Ahh. The hunger pangs are getting stronger now. Classic explanation though! *-*

  • Mo Leily 6 years ago

    Thank you so much it’s was very useful

  • LJ2190 6 years ago

    If you exchange the chocolate for materials which showed similar lines, which would be most suitable for a) a lift cable? And b) a bungee jump?

  • Ang badang 6 years ago

    This is by far your worst video in my opinion, I am trying to cram for an exam and all I want is a Crunchie haha

    • lowkeylean 6 years ago

      Ang badang i dont think this is for last minute study….its only for the basic understanding

    • Ang badang 6 years ago

      @Castillo Dazš It was more of a last minute reminder of basic principles. The exam was only A level which isn’t too in depth on everything as it tries to cover a lot.

  • Nav Raja 6 years ago

    Arnt you going to do a video on springs in series or parallel?

    • Physics Online 6 years ago

      I don’t think I’ve done this – but that is a tricky area (and useful when you also consider resistors and capacitors in parallel). Very good idea.

  • Amara Mansoor 5 years ago

    HE BREAKS THE CHOCOLATES SO SLOWLY LIKE AN ADVERTISEMENT GIVE ME THE CHOCOLATE

  • Sticknado 5 years ago

    And that kids is why Mars bars>Crunchie bars

  • marc manley 5 years ago

    Real things like metal ? dont disrespect wham bars like that man

  • Hrithik George 5 years ago

    Whenever possible, I’ll try and do this experiment. You know… for repetitive quality testing purposes.

    I’ll need the gym now…

  • Navid Mohammadzadeh 5 years ago

    I like it. Thanks

  • Erick Carvalho Campos 5 years ago

    Brilliant video! I like the simple way you figure it out to explain the concepts.

  • ORLOGSKAPTEIN A 5 years ago

    Children in Africa could’ve eated that wire

  • daniyal warraich 5 years ago

    Thankyou !

  • Trve Kvlt 4 years ago

    Stop with the food analogies! You are making us all hungry

  • GD_Mantesh 4 years ago

    u great mate! cz when u do experiment we learn easily than speaking too much .. Thanks for this vid

  • Iamyou iamyou 4 years ago

    i watch this video while fasting in ramadan, crunchies are also my favourite

  • Pong 4 years ago

    damn youre good at this

  • Adilwani6159 Wani 4 years ago

    Great one ,

  • DoG TooTH 4 years ago

    Came here to solve physics problems. Made me to go to the store and buy some crunchies.

  • Sunny kim 4 years ago

    Uve just made me hungry

  • Uma Kumaravel 4 years ago

    ASMR to its finest! Great video!

  • IAET 4 years ago

    BEST WAY #AWESOME!

  • Skywalker 3 years ago

    neat examples & explanation! i don’t go here (physics), but i got it super fast thanks to you!

  • Haider's Tech 3 years ago

    That was a very good video, Thanks a lot 💓💓

  • Benchley Banawag 3 years ago

    Simple demonstration and yet verry understandable

  • Spyroxin 3 years ago

    A brief video, totally to the point without any room for boredom. Simply amazing.

    • Physics Online 3 years ago

      Thanks. I try to keep it simple while still covering everything you need to know.

  • Sabrina Islam 3 years ago

    I just got a kitkat ad

  • Elite a20 3 years ago

    How can you find out if a material is tough or strong from the graph?

  • EmilySB 2 years ago

    I came here to learn. I left here hungry.

  • MReza Tahan 2 years ago

    I enjoyed the simple illustration. Good job!
