Question

For the state of stress shown in the below figure, normal stress acting on the plane of maximum shear stress is

• A. 25 MPa compression
• B. 75 MPa compression
• C. 25 MPa tension
• D. 75 MPa tension

Answer 1

The correct option is C 25 MPa tension

Normal stress on the plane of maximum shear stress
$\frac{{\sigma }_1+{\sigma }_2}{2}=\frac{100-50}{2}$
= 25 MPa (tensile)
