Two-dimensional state of stress at a point in a plane stressed element is represented by a Mohr circle of zero radius. Then both principal stresses

- a)Are equal to zero
- b)Are equal to zero and shear stress is also equal to zero
- c)Are of equal magnitude but of opposite sign
- d)Are of equal magnitude and of same sign

Correct answer is option 'D'. Can you explain this answer?

Radius in principle plane gets zero so according to the formula (sigma 1 - sigma 2 )Ã·2 = 0

sigma 1 = sigma 2

sigma 1 = sigma 2
