Euler Theory for Buckling Failure

The Swiss Mathematician Leonhard Euler in 1757 derived a formula for stability of long column. According to Euler’s theory, long

Solid circular shaft Hollow circular shaft Di = internal diameter Do = outer diameter Thin circular tube with mean radius

Principal Strains These are strains on planes on which shear strains vanishes and values of shear strains are maximum and

Consider a plane stress element is shown in figure. In this stress element σz = 0 σyz = 0 τxz

For an economical design, the section of the beam may be reduced towards the support, as bending moment decreases towards

A beam that is built from more than one material is known as composite beams. Example are bimetallic beams, flitched

(a) Principal Stress Consider a planar stress element subjected to normal and shear stress as shown below. Normal stress and

Consider a simply supported beam AB of length L subjected to moment M0 at its ends as shown in figures.

Shear force and bending moment diagrams represent variation of shear force and bending moment along the beam. Shear force diagrams

Following points should be kept in mind during construction of loading diagram from the corresponding bending moment diagram. If an

The fundamental concept of stress can be understood by considering a prismatic bar that is loaded by axial force P
