A solid circular bar of steel (G = 11.4 ( 106 psi) with length L = 30 in. and diameter d = 1.75 in. is subjected to pure torsion by torques T acting at the ends (see figure).
(a) Calculate the amount of strain energy U stored in the bar when the maximum shear stress is 4500 psi.
(b) From the strain energy, calculate the angle of twist ( (in degrees).
