Certain strains and angles are given for a point in a body subjected to plane strain. Determine the unknown quantities and sketch the principal strain deformations and the maximum in plane shear deformation. $($hint $-$ use the equations for Mohr's circle to find ${}_{\text{a}\text{v}\text{g}}$ and R$).$

${}_y=-880({10}^{-6}),{}_{p2}=?$
