When tanθ multiplied by normal stress we obtain the value of tangential stress.

So, option C should be the right answer.

Normal stress = pcosθ2(a).
Cosθ2(a) *tan(a)=cos(a)sin(a) = sin(2a)/2.
So, by multiplying tan(a) to normal stess we get. P/2*sin(2a) which is tangential stress.

It will be D in terms of the applied normal stress.

But if we need to find in terms of the normal stress produced on the same plane on which we need to find shear stress then we need to multiply by cot θ.

@Rakesh Ojha.

Your expression is about normal shear stress.

Narayan ch.saha said:   4 years ago
The Correct answer is E. I agree with the given answer.

Dilip Yadav said:   5 years ago
The Correct answer is D.

Rakesh Ojha said:   5 years ago
It will be D.

TS = σ/2 *sin2x = σ/2 *( 2sinxcosx).
= σ* sinxcosx.
