Question: A solid circular bar of diameter d = 1.5 in. is subjected to an axial force P and a torque T (see figure). Strain gages

A solid circular bar of diameter d = 1.5 in. is subjected to an axial force P and a torque T (see figure). Strain gages A and B mounted on the surface of the bar give reading
(a = 100 ( 10-6 and (b = - 55 ( 10-6. The bar is made of steel having E = 30 ( 106 psi and v = 0.29.
(a) Determine the axial force P and the torque T.
(b) Determine the maximum shear strain (max and the maximum shear stress tmax in the bar.
