Question
For the plane stress situation shown in the figure, the maximum shear stress and the plane on which it acts are:
Correct answer
(D) Zero, at all orientations
Solution
The stress state shown is MPa, MPa, and . The principal stresses are MPa. The maximum in-plane shear stress is given by . Since the Mohr's circle for this state of stress is a single point on the -axis, the shear stress is zero on all planes regardless of orientation.
