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 )÷2 = 0
sigma 1 = sigma 2
