A line shaft is supported between bearings with one overhung pulley. The pulley on the line shaft is 1.0 m in diameter and has vertical belt tensions of 5.4 kN and 1.8 kN. What is the torque transmitted by the shaft?

A shaft is subjected to a maximum torque of 12 kN·m and a maximum bending moment of 16 kN·m at a particular section. What will be the diameter of the shaft according to the maximum shear stress theory (Guest and Tresca's theory) if the elastic limit in simple tension is 160 MPa? [Take (4/π)1/3 = 1.08]
