A rod with 100-mm diameter is loaded as shown. a-Find stresses at points A and B on the surface of the rod and sketch the stress elements at these points. Show the axes of each element. b-Use Mohr's Circle to find principal stresses and maximum shear at the most critically stressed point. Plot the results on elements, showing the orientation with respect to the original axes.
