Homework Help: Pressure on an iron black

  1. Oct 27, 2008 #1
    How much pressure is needed to compress the volume of an iron block by 0.16 \%? Express your answer in {\rm{N/m}}^2.

    I know pressure is the same as stress, and that stress is force/csa. Could someone point me in the right direction.

    Look up the relation between stress and strain.

    Also, you will need the value of Young's modulus for iron.
