5-63 Problem 5-63 The figure shows a shaft mounted in bearings at A and D and having pulleys at B and C. The forces shown acting on the pulley surfaces represent

the belt tensions. The shaft is to be made of AISI 1035 CD steel. Using a conservative failure theory with a design factor of 2, determine the minimum shaft diameter to avoid yielding. 1200 N 150-mm D. 200 N 200 mm 200 mm D. B 200 mm 120 N 1600 N D 150 mm
