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.

DERIVATION & ITS SIGNIFICANCE
Deformation Processes In these processes, the material is plastically deformed (hot or cold) under the action of an external force, to produce the required shape. No material i
Find the tension in the thread: A thread is wound round a heavy homogeneous cylinder of mass m and radius. The cylinder is permitted to fall from rest and unwinds the thread.
