Question

The state of stress at a point P in a two dimensional loading is such that the Mohr's circle is a point located at $175MPa$ on the positive normal stress axis.

The directions of maximum and minimum principal stresses at the point P from the Mohr's circle are

• A. 0, ${90}^o$
• B. ${90}^o$, 0
• C. ${45}^o$, ${135}^o$
• D. All directions

Answer 1

The correct option is D All directions

Mohr's circle is a point, hence maximum and minimum stress at point P is same in all directions.
