Problem I. A homogeneous, graded shaft with circular cross section is clamped at both ends and loaded by the torque Mo (see table of values). Use a = 2 m, b= 3 m, r = 25 mm, r2 = 40 mm, and G = 77.2 GPa. a) Compute the torques at the support positions A and B. b) Compute the angle of twist at the point where Mo is applied. 2r1 2r2 A Мо В a
