The design of the gear-and-shaft system depicted necessitates the use of steel shafts of the same

diameter for both AB and CD. It is also necessary that the maximum pressure be 60 MPa, and that

the angle D through which the end D of shaft CD turns not exceed 1.5°. Determine the needed shaft

diameter using G = 77.2 GPa
