The shaft ABC' shown in the Figure Q2(a) is driven by a motor that delivers 300 kW at a rotational speed of 32 Hz. The gears at B and C' take out 120 and 180 kW, respectively. The lengths of the two parts of the shaft are Li = 1.50 m and L: = 0.91 m. Determine the required diameter, d of the shaft if the allowable shear stress is 50 MPa, the allowable angle of twist between points A and C is 4.0°, and G = 75 GPa.
