Question

A small element at the critical section of component is in a bi-axial state of stress with the two principal stresses being 360 MPa and 140 MPa. The maximum shear stress is

• A. 220 MPa
• B. 180 MPa
• C. 314 MPa
• D. 330 MPa

Answer 1

The correct option is B 180 MPa

Absolute max shear stress is max of
max $[\frac{360}{2},\frac{140}{2},\frac{360-140}{2}]=180MPa$
