Question

For the plane stress shown in figure, the maximum shear stress and the plane on which it acts are :

• A. -50 MPa on a plane ${45}^o$ clockwise w.r.t. to x-axis
• B. -50 MPa on a plane ${45}^o$ anti - clockwise w.r.t to x-axis
• C. 50 MPa at all orientation
• D. Zero at all orientation.

Answer 1

The correct option is D Zero at all orientation.

Mohr Circle is a point

Hence shear stress at all orientations is zero.
