A beam with a circular cross section of diameter D and length L is fixed at a wall. Calculate (i) the position of the maximum stress along the length of the beam, (ii) the position of the maximum stress radially within the beam, and (iii) the magnitude of the maximum stress (in terms of the variables given in the problem) for each of the following:a. Normal stress due to axial load Fab. Shear stress due to torque T c. Normal bending stress due to radial load Frd. Shear bending stress due to radial load Fr
