Beams and cantilevers are subjected to transverse loads, producing bending moment and shear force in beam/cantilever section. In Chapter 8, stress distribution due to bending moment along the depth of the section is analysed showing maximum stresses in outer skin of the beam. In this chapter, shear stress distribution along the depth of the section will be studied. For some sections, shear stress at the neural axes of the section is maximum, while bending stress is zero at the section.
Basic objective of this chapter is to make the student learn about shear stress at any layer of beam section which depends upon the first moment of the area above the section or below the section depending upon ...
