A circular shaft transmits power as shown with pulley loads. The shaft carries a torque, bending, shear and axial loads. Draw LVM diagram to find Mmax and Vmax. Show all loads (moments and forces) on the circular x-section of the shaft below. Use double arrows for moments. Compute shear and normal stresses and show them on the same section. Create stress elements for points A and B of the section. Combine the stresses and compute tmax (Tresca) and om (von...
