Homework Help: A2 Practical Project. Stress, Strain and. . . I need help with the set up.

  1. Dec 2, 2009 #1
    For my A2 practical project I am using a stress gauage on a 'rule' shape of plastic and adding diffrent weights to see the changein stress and strain. As another varible I will be changing the temperture of the plastic to see how this effects its stress and strain.

    I'm looking for help in how I should set the experiment up? (words, diagrams or web links)
    What other things I should measure?
    Examples of this experiment?
    Gernal advice and tips?

    p.s. I chose this experiment as I plan to study Civil Engeerning at university.

    Relevant equations:-
    Youngs modulas- E = σ2 - σ1 / ε 2 - ε 1
    All that I can think of.

    The attempt at a solution:-
    I've asked my teacher for help but it wasn't sucesful.
    I've looked on the internet but found nothing usfull so far. . . .

    thanks, tom. . . my email:- [<< personal e-mail address deleted by berkeman >>
