Question

Using formula of Generalized hooke's law

A sheet of copper is stretched biaxially in the xy-plane. If the strains in the 0.40 x 10-3 and e, 2.30 sheet are €x = 0.30 x 10-3, determine ox and o,. Use E = 110 y• GPa and v 0.35. The normal stresses at a point in a steel member are ox = 10 ksi. Using E = 29 × 10³ ksi and v = 8 ksi, oy 0.3, determine the normal strains at 2.31 -4 ksi, = and oz = this point. 2.32 The rectangular block of material of length L and cross-sectional area A fits snugly between two rigid, lubricated walls. Derive the expression for the change in length of the block due to the axial load P.
