    1. The problem statement, all variables and given/known data
    Based on the data in Table 1.3 of Hertzberg, estimate the elastic modulus of an iron single crystal along the [2 1 -3] direction. Express your answer in GPa in the form yyy.y

    S11=0.80, S12=-0.28, S44=0.86 (10^-11Pa^-1)
    2. Relevant equations
    1/E=S11-2((S11-S12)-.5*S44)(l1^2*l2^2+l2^2*l3^2+l1^2l3^2)


    3. The attempt at a solution

    1/E=0.80-2((0.80-(-.28)-.5(0.86))(.25)
