Q. A plate in equilibrium is subjected to uniform stresses along its edges with magnitude ππ₯π₯ = 30 MPa and ππ¦π¦ = 50 MPa as shown in the figure
The Youngβs modulus of the material is 2Γ1011 N/m2 and the Poissonβs ratio is 0.3. If ππ§π§ is negligibly small and assumed to be zero, then the strain ππ§π§ is
