Determine an appropriate size for a square cross-section solid steel shaft to transmit 260 hp at a speed of 550 rev/min if the maximum allowable shear stress is 15 kpsi.

46.05 mm

Explanation:

Given

speed

allowable shear stress

Power is given by

From Torsion Formula

where J=Polar section modulus

T=Torque

=shear stress

For square cross section

where a=side of square
