Determine the diameter of a solid shaft which will transmit 200 kW at 150 rpm. The maximum shear stress should not exceed 63N/mm2 and the twist should not be more than 20 in a shaft length of 10.6meter. Take modulus of rigidity = 1 x 105 N/mm2.

A cantilever of 14m span carries loads of 41kN, 8kN and 39 kN at 3m, 7m and 14m respectively from free to fixed end. It also has a uniformly distributed load of 3kN/m run over the entire length. Draw the shear force and bending moment diagrams

**Expert’s Answer:**

Note: part 2 of this question for which angle of twisting has been not written perfectly in question. So I have considered 2 degree in 10.6 m shaft length.

Concept will remain same you just need to change your actual value
