Question
A solid circular bar with a diameter of
d = 1.25 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 readings e = 140 X 10_b
ande8 = —60 X 10_6. The bar is made of steel having
E = 30 X 106 psi and y = 0.29.
(a) Determine the axial force P and the torque T (b) Determine the maximum shear
strain and the maximum shear stress in the bar
