A differential element is subjected to plane strain that has the following components: (epsilon_{x}=950left(10^{-6} ight), epsilon_{y}=420left(10^{-6} ight)),

A differential element is subjected to plane strain that has the following components: \(\epsilon_{x}=950\left(10^{-6}\right), \epsilon_{y}=420\left(10^{-6}\right)\), \(\gamma_{x y}=-325\left(10^{-6}\right)\). Use the strain transformation equations and determine

(a) the principal strains and

(b) the maximum in-plane shear strain and the associated average strain. In each case specify the orientation of the element and show how the strains deform the element.
