Q.3) The motor attached to the left-end of a steel (G= 11x10³ ksi) shaft AB delivers 60 hp which rotates the shaft AB at 18 Hz. The gears at C and D fixed to the staft AB transmit 40 hp and 20 hp to attached machinery, respectively. The shaft AB is supported on smooth bearings at A and B, which allow free rotation of the shaft. If the allowable shear stress in shaft AB is 10 ksi and the allowable angle of twist of D with respect A is 0.3 degree, determine the diameter of the shaft. 12 inch 10 inch 8 inch

Question
Q.3) The motor attached to the left-end of a steel (G= 11x10³ ksi) shaft AB delivers
60 hp which rotates the shaft AB at 18 Hz. The gears at C and D fixed to the
staft AB transmit 40 hp and 20 hp to attached machinery, respectively. The
shaft AB is supported on smooth bearings at A and B, which allow free rotation
of the shaft. If the allowable shear stress in shaft AB is 10 ksi and the allowable
angle of twist of D with respect A is 0.3 degree, determine the diameter of the
shaft.
