    Okk.. basically, I have just been set Physics coursework and its due in next week so in a slight panic. I am doing OCR B... we need to make a presentation on a material of our choice.

    I have decided to base mine on: 'why do we use nitinol in orthodontics'

    all was going well until i got to the calculations.. I need to talk about youngs modulus, tensile strength, super elasticity etc but I also need to show the calculations for this. I have no raw data so I have nooo idea how I'm supposed to work it out?! I emailed my teacher and she just said to work backwards...!

    So, is there anyone who is doing this or has done something similar??

    Would love it if someone could help me out! Thanks
