Theory of Simple Bending
CHAPTER OBJECTIVES
A relationship between the bending moment on a section of a beam and the normal stress developed in a particular layer of the beam section will be derived. Students will learn about the flexure formula, a relationship between bending moment, normal stress and second moment of area.
Different sections of the beam such as square, rectangular, I, T, channel and circular will be considered and stress distribution along the depth of the section will be plotted. Stresses in built up sections and in composite beams will also be analysed. Students will also learn about the stresses developed in reinforced cement concrete (RCC) beam.
Introduction
Stress in various sections of the beam will be determined ...
