5-69. The A-36 steel bolt is tightened within a hole so that the reactive torque on the shank AB can be expressed by the equation 1 = (kx²) N. m/m, where x is in meters. If a torque of T = 50 N·m is applied to the bolt head, determine the constant k and the amount of twist in the 50-mm length of the shank. Assume the shank has a constant radius of 4 mm. 5-70. Solve Prob. 5-69 if the distributed torque is t = (kx²/³) N-m/m.
