Q1: A motor driving a solid circular steel shaft transmits 30 kW to a gear at B (as shown). The allowable shear stress in the steel is 40 MPa.. G=70 Ga (a) What is the required diameter d of the shaft if it is operated at 1500 rpm? (b) What is the required diameter d if it is operated at 3000 rpm? (c) If the length of the shaft from the motor to the gear is 1 m, what are the angles of twist for the two speeds of rotation?
