Example of maximum bending stress equation
WebTo design a shaft you need to be able to find the equivalent maximum stress resulting from the bending stress and the shear stress. However, you cannot simply add tensile (or compressive) and shear stresses together directly. The procedure for finding the maximum equ1valent stress is outlined in the following sections. 5. Stresses on a Cutting ... WebThe maximum stress occurs at the surface of the beam farthest from the neutral axis. This is called "maximum surface stress" and is typically represented by the sigma sign. In order to calculate maximum surface …
