The state of strain at the point on the bracket has components of \(\epsilon_{x}=-130\left(10^{-6}\right), \quad \epsilon_{y}=280\left(10^{-6}\right)\), \(\gamma_{x y}=75\left(10^{-6}\right)\). 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.
