Задача id13391

Determine the ratio of the deformation energies of steel and plastic cylinders placed next to each other and compressed between parallel planes, if before deformation they had the same dimensions. Young's modulus for steel - 2 • 105 N/mm2, for plastic - 102 N/mm2. Determine the same ratio for the case when the cylinders are placed on top of each other and compressed by the same planes.
