Problem (check ) :

A hollow steel shaft has an external diameter of 500 mm and an internal diameter of 250 mm-
The shft transmits 25 x 10^3 kW a t 160 rpm .

a) What angle of twist is expected for a length of 2.5 m for a mdolus of rigidity of the material of 75 KN / mm^2 ?

b) What diameter of solid shaft will transmit the same power at the same maximum stress? and

c) What will the ratio of the angle of twist be to that of the hollow shaft if the maximum shear stress in the material of 75 N / mm ^2 and what is the ratio of actual permissible shear stress?
