Strain on Cantilever beam

  1. Dec 15, 2011 #1
    Hey everyone, I'm having some trouble with my material science homework. I really have no idea where to begin:

    Consider a piece of beam of 1 cm in length with one end fixed on
    a wall and the other end free (see illustration below). If you bend the beam by
    applying a force at the free end that is perpendicular to the beam, it bends by about
    0.5 degree.
    a. How large is the strain?
    b. What is the displacement at the end and in the middle of the
    c. Is the strain at the free end the same as that in the middle of the
    d. Do you expect the beam to get longer if you bend it further but
    still elastically?
