A plane element in a body is subjected to a normal stress in the x direction of 80 MPa, as well as a shearing stress of 30 MPa, as shown in the figure below. Determine: a) The normal and shearing stress on a plane inclined at an angle of 30 degrees to the normal stress b) Maximum and minimum values of normal stress that may exist on inclined planes and directions of these stresses.

For the state of plane stress shown, determine the maximum shearing stress when $(a) \sigma_{x}=20 \mathrm{ksi}$ and $\sigma_{y}=10 \mathrm{ksi},(b) \sigma_{x}=12 \mathrm{ksi}$ and $\sigma_{y}=5$ ksi. (Hint: Consider both in-plane and out-of-plane shearing stresses.
