## Homework Statement

For the state of stress shown in the figure, normal stress acting on the plane of maximum shear stress is?

## Homework Equations

Normal stress σ

_{n}= σcos

^{2}θ

3. The Attempt at a Solution

3. The Attempt at a Solution

Plane of maximum shear stress is 45

^{o}relative to the max stress of 100MPa.

So the total normal stress is 75MPa (compression).

I have assume the direction of normal stresses in both the cases with respect to applied stress.

Have I assumed the direction in both cases correctly?

Thanks in advance!
