Задача 10265.

A building structure weighing m=5 tons is suspended by two solid iron rods L=2 m long and d=2 cm in diameter. Determine the normal stress, absolute and relative elongation, as well as the potential energy P of elastically deformed rods. Ignore the weight of the rod. Young´s modulus E=200 GPa.

A detailed solution with a brief note of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
