A 50-mm-square plate is subjected to the stresses shown in Fig. P2.36.What deformation is experienced by diagonal BD? Express the solution, in terms of E, for v=0.3 using two approaches: (a) determine the components of strain along the x and y directions and then employ the equations governing the transformation of strain; (b) determine the stress on planes perpendicular and parallel to BD and then employ the generalized Hooke’s law.
