Combined Loading Problem – Determine the STATE OF STRESS at points A and B

A methodical approach to a combined loading problem to ensure that you never forget a loading and that you add or subtract terms to correctly determine the state of stress. For problems asking you to “Determine the State of Stress that the combined loading produces” or “Determine the stress components”, the two main challenges are figuring out which terms need to be used, and whether each term should be added or subtracted. To never forget a term, consider that every applied force or moment could cause loading about any axis, in normal or shear, at any point of interest. This is a lot of possible terms to consider – but as you’ll see in the video, most of them can be ruled out very quickly.
