When pushing off horizontally from a pool wall with her legs, the resulting force of the wall on the swimmer can be considered to act parallel to the length of her femur (thighbone), compressing it 2.98 × 10–5 m. The bone is equivalent to a uniform cylinder that is 36.0 cm long and 1.82 cm in radius. Young's modulus for bone is 1.60 ✕ 1010 N/m2. (a) Calculate the force exerted on the bone. N (b) If her mass is 75.0 kg and water resistance is negligible, what is her acceleration (in m/s2)? Assume her weight is precisely supported by the buoyant force of the water. m/s2

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).
