Problem 3.3-7 A circular tube of aluminum is subjected to torsion by torques T applied at the ends (see figure). The bar is 20 in. long, and the inside and outside diameters are 1.2 in. and 1.6 in., respectively. It is determined by measurement that the angle of twist is 3.63° when the torque is 5800 lb-in. Calculate the maximum shear stress t max in the tube, the shear modulus of elasticity G , and the maximum shear strain g max (in radians).
