A piece of copper having a rectangular cross section of \[\theta \]mm x \[\theta >{{90}^{o}}i.e.\] mm is pulled in tension with 44,500 N, force producing only elastic deformation. Calculate the resulting strain. Shear modulus of elasticity of copper is \[{{\text{S}}_{\text{SA}}}\text{}{{\text{S}}_{\text{SL}}}\text{,}\]

Answer:

Here, \[\theta \]                             \[\theta <{{90}^{o}}i.e.\]                 \[\cos \theta \]\[\theta \]                 \[\theta \]
