problem: A thin isotropic metal plate is subjected to the plane stress state shown (properties of the metal are: E = 10 x 106 psi and ν = 0.250).  A uniaxial strain gage is mounted on the plate (properties of the strain gage are Sg = 2.00, Kt = 5%).  The gage is wired into a P-3500 strain gage indicator, and a gage factor setting of 2.00 is used.  Predict the strain measurement returned by the strain indicator
