A circular shaft transmitting 100 kW of power at 150 rpm is supported in bearings that are 4 meters apart. At the mid span, it carries a pulley that exerts a transverse load of 16 kN on the shaft. Determine the minimum diameter of the shaft if the stress acting alone would produce the maximum strain, is not exceeding 120 N/mm2 and the poisson’s ratio is 0.25 .
