    stress/strain graph shows youngs modulus which is used to measure the stiffness of the elastic material
    compare springs in parallel and springs in series
    the parallel stretch half as much as a single of the same spring
    and a series one stretches twice as much as the same single spring
    this shows that the extension depends on the area of where the force is acting

    so to compare results fairly you use youngs modulus (stress/strain) instead of force/extension to measure the stiffness of a material accurately

    from the origin to p (limit of proportionality) the graph obeys hookes law as stress(Force) is proportional to stress(extension).
    At E its the elastic limit where beyond this point the material will not return back to its original length (so behaves plastically).

    UTS is the maximum stress until the material breaks

    when comparing materials, the material (line) that has a big change in the x axis (strain) means it acts elastically more e.g copper
    if a material has a big change in the y axis (stress) but no big change in the x axis then it is very brittle and doesnt stretch rather breaks suddenly

    stress and strain graphs
    If u were to draw the graphs and label every point of the graph and info, like what the gradient means etc.
