Strength of Materials is a comprehensive book for undergraduate students studying Mechanical or Civil Engineering. The book teaches students how materials bear loads and how they react under loads. It teaches them how to analyse the stresses in materials, explaining the phenomena of elasticity and plasticity. Going further, it explains how bodies break, and the various types of failure that can occur. It covers advanced topics such as beams, columns and shafts, discussing Euler’s formula, Rankine’s Formula, and Mohr’s Circle. The book teaches students how to solve various kinds of problems which appear in examinations repeatedly, and gives them a vital understanding of the underlying theory.
