Question

A two-dimensional stress system has like stresses ${\sigma }_x=100N/m{m}^{2}and{\sigma }_y=200N/m{m}^2$ in two mutually perpendicular directions. The x, y, co-ordinates of the centre of the Mohr's circle are

• A. (0, 150)
• B. (150, 0)
• C. (-50, 0)
• D. (50, 0)

Answer 1

The correct option is B (150, 0)

The x and y co-ordinates of centre of Mohr's circle are given by
$(\frac{{\sigma }_x+{\sigma }_y}{2},0)=(\frac{100+200}{2},0)=(150,0)$
