A is thw right ans.. as extremities of dia. are points of principal stresses.. since extremities means the end points of the dia. Which shows the principal stresses.. normal stress is at the point in sumwhere b/w the dia.. bt not the extremities

Any extremities of diameter pass through centre of mohr's circle so centre of mohr circle gives normal stresses on plane at 45 degree.

Option D is correct, I think.

Rizwan you got this actually at any point on the mohr's circle represents the maximum shear stress and maximum stress is at the plane 45° to the normal stress plane.
Right answer is 'B'.

M. Rizwan said:   8 years ago
The option B is correct because at 45 degrees Mohr's circle will take it as 90 degrees. So at this angle normal stress will be equal to the maximum shear stress which is radius on any point of mohr's circle.

D Option is correct as the x- coordinate in Mohr's circle contains the normal stress but the Y Axis also contain the shear stress values.

Amar said:   8 years ago
Which one is the correct answer? Explain.

Vijay kumar said:   8 years ago
It gives both normal and shear.

Sandiarta said:   8 years ago
Why is it B? I think it should be D.

I think option D is correct.
