Question 2 The vertical shaft and the pulleys keyed to it in Figure Q2 may be regarded as weightless. A constant angular velocity is used to rotate the shaft. The known belt pulls are shown, and the three pulleys are firmly keyed to the shaft. Calculate the required diameter of a solid circular shaft if the operating stress in shear is 50 MPa. Because the bearings and pulleys are close together, neglect shaft bending. 250 mm 350 mm 1 -500 mm- -3 kN 1 kN 1 kN 1.25 KN
