Question

What is the diameter of Mohr's circle of stress for the state of stress shown below?

• A. 20
• B. 10$\sqrt{2}$
• C. 10
• D. Zero

Answer 1

The correct option is D Zero

Radius of Mohr's circle
$=\sqrt{{\left(\frac{{\sigma }_x-{\sigma }_y}{2}\right)}^2+{\tau }_{xy}^2}$

$=\sqrt{{\left(\frac{10-10}{2}\right)}^2+0}$
= 0
