A car is driving down the road and goes over a speed bump. The car has a solid circular drive shaft that is subjected to a tensile axial force of F = 300 kN, a bending moment of M = 5.0 kN m, and a torque of T = 9.0 kN m as a result of the bump. The shaft has a diameter d = 6.6 cm and mechanical properties of E 200 GPa, v = 0.35 and = Oy = 350 MPa. a. What and where is the maximum stress? Hint: use the principle of superposition.
