At a point in a load carrying member, the state of stress is as given below.

\[ \sigma_{x}=400 \mathrm{MPa}, \sigma_{\mathrm{y}}=-300 \mathrm{MPa}, \tau_{\mathrm{xy}}=200 \mathrm{MPa}(\mathrm{ccw}) \]

Draw the Mohr's circle and find the principal stresses and principal planes. Also draw the principal and maximum shear stress elements.
