Strength of Materials

By Kibret Alemayehu

The previous studies were confined to direct stresses caused on planes at right angles to the line of action of applied loads and to shear stresses. In this chapter we advance our studies to the stresses caused on planes inclined to the line of action of applied loads. However complex the system of forces acting on a body be, yet it is possible to locate three mutually perpendicular planes which carry purely normal stresses. Planes within a material such that the resultant stresses across them are wholly normal stresses or planes across which no shearing stresses occur are termed as principal planes and the stresses acting on these planes are called principal stresses. The stress intensity on one of these planes at a point is more than on the other two planes and on the other one it is least of all. Below we proceed to investigate a few typical cases.
