Thestate of strain at the point on the spanner wrench has componentsεx = 260(10-6), εy = 320(10-6), γxy= 180(10-6). Use thestrain-transformation equations to determine (a) the in-planeprincipal strains and (b) the maximum in-plane shear strain andaverage normal strain. In each case specify the orientation of theelement and show how the strains deform the element within the x-yplane.
