Question

For the beam shown below, at each cross section of a-a, b-b and c-c, consider two points in the cross section at the middle and bottom of the section (points A and B on the right figure). Note a-a is a section very close to the left end of the beam. Sketch the stress elements by showing normal and shear stresses and indicate the coordinate system. Represent the stresses as functions of force and dimensions.
