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 t = (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. the shear modulus of elasticity for a-36 steel is 75 gpa.
