The state of strain at the point on the support has components of ε_x= 350(10^-6), ε_y= 400(10^-6),

γ_xy = -675(10^-6). Use the strain-transformation equations to determine (a) the in-plane principal strains and (b) the maximum in-plane shear strain and average normal strain. In each case specify the orientation of the element and show how the strains deform the element within the x€“y plane.
