The shaft, as given in Figure is driven by pulley B from an electric motor. Another belt drive from pulley A is operating a compressor. The belt tensions for pulley A are 1500 N and 600 N. The ratio of belt tensions for pulley B is 3.5. The diameter d of pulley A is 150 mm and the diameter d of pulley B is 480 mm. The maximum allowable tensile stress for the shaft material is 170 MPa and the allowable shear stress is 85 MPa. Taking bending and torsion factors as 1.25 and 1.75 respectively, Evaluate the shaft diameter. Also search out the dimensions for a hollow shaft with outside diameter limited to 30 mm. Compare the weights of the two shafts.
Define the nature of shear force and bending moment under load variation. Sol.: The nature of SF and BM variation under two-load region is given in the table below
Kinematics: This is that branch of Theory of Machines that deals with the relative motion among the several machine parts; without referring forces or torques that cause motion.
Determine the analytical solution for the maximum stress of the beam shown; compare with stress results from SolidWorks. Draw shear and moment diagrams and print them from the beam
