Torsional Stresses, Strains, and Rotations

Abstract

A major part of this chapter is concerned with shearing stresses and angles of twist of circular and hollow circular cylindrical shafts subjected to torques. Mathematically, this is the simplest torsion problem and an important practical one because such sections resist torque efficiently. Principal stresses and strains in shafts are evaluated with the aid of the Mohr’s circle construction. Elements taken from shafts are usually free of stresses on the surface, and the analysis reduces to one of plane stress.
