Abstract

A comparison of an exact calculation of maximum stress in a cylindrical rod under torsion is compared to the usual engineering approximation which takes the maximum stress as that existing on the boundary of the largest circle inscribed in the given cross section. A numerical example for a symmetrical thin double wedge cross section is calculated and essential agreement in stress magnitude found, although there was an eight degree difference in the location of the point of maximum stress.
