    Showing resultant stresses on a volume element

    Me again, (this is what happens when you make a designer do mechanics, and give her a lecturer she doesn't understand :P ). I'm stuck on a combined loadings question. This is the question: "The 60 mm diameter rod (fixed at end C on the wall) is subjected to the loads shown. 1) Transform...

    Finding minimum yield strength from Mohr's circle and von Mises stress

    :blushing: You're absolutely right, I didn't register that the question was asking me for the max-shear-stress theory not max-distortion energy! Silly mistake! But thank you :D

    Finding minimum yield strength from Mohr's circle and von Mises stress

    Woops might have been an idea to state that in the first place! Sigma-x was 560MPa, sigma-y 0MPa and tau-xy was 175MPa.

    Finding minimum yield strength from Mohr's circle and von Mises stress

    Hi Wasn't sure where to post this, hope it's ok in here! I've gotten myself very confused as to how to find the minimum yield strength for an element. I have used Mohrs circle to find sigma1 and sigma2, then plugged that into the von mises equation to find sigma-von = 636.8MPa. The...
