Given the plane stress state shown for the material point element, use any calculation method $($graphical is fine too$)$ to determine:

a$)$ The maximum in$-$plane shear stress

b$)$ The components of stress at the point when the element is cut out $($oriented$)60$ degrees counterclockwise to the element shown. Draw the components on the element at right.

You may tear out the to$-$scale $60$ degree angle at right
