Question: the part shown is loaded at point b with 40...

Question details

The part shown is loaded at point B with 40 lbf in the negative y direction, and at point C with 60 lbf in the positive y direction. Evaluate the likelihood of failure in section AB by providing the requested information. (a) Sketch the critical stress element in 60 Ibf 0.8-in dia 40 Ibf section AB. Calculate and show the stresses applied to the critical stress element 4 in (b) Sketch the Mohrs circle for the critical stress element, approximately to scale. Label the locations of all three principal stresses, and the maximum shear stress in 1n
