Problem (check ) :
A hollow steel shaft has an external diameter of 500 mm and an internal diameter of
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 ?
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 ?
This solution is comprised of a step by step explanation of torsional stress, torsional strain and relationship with modulus of rigidity & polar moment of inertia for hollow shaft & solid shaft.
