As shown, a shaft is composed of five cylindrical sections. A motor is attached at F and supplies the shaft with P = 165.0 kW at a speed of w = 180 rad/s. This power is transferred through the shaft without any loss and is completely removed by the pulley at A. Let a = 0.200 m, b = 0.270 m, c = 0.390 m, d = 0.080 m, d2 = 0.145 m, and d3 = 0.200 m . Assume that the modulus of rigidity for the entire shaft is G: = 75.8 10 Pa and that the sections of the shaft are fastened in such a way that they cannot fail. Also, assume that the shaft is rigidly supported along its length such that it is always in static equilibrium. = b B d E d
