The shaft shown in the following figure is supported by smooth journal bearings at A and B. Due to the transmitted power to and from the shaft, the belts on the pulleys are subjected to the tensions shown. If you know that the shaft is made of a material having allowable shear stress of 50 MPa, it is required to do the following: 1- Draw the free-body diagram of the shaft. 2- Find the induced moment at pulleys C and D. 3- Find the reactions at bearings A and B. 4- Draw the shear force, bending moment (M, and M.) and torque diagrams. 5- Analyze the drawings to find the critical point sin the shaft. 6- Use the maximum-shear-stress theory to find the shaft diameter (choose the shaft diameter according to standard). 0.250 m 0.050 m 300 N 200 N 550 N 0.250 m 400 N 0.150 m D 0.075 m DFocus 20 ENG US 28/
