A hammer strikes a metal disk with 150N of force, temporarily making the 25.0mm3 disk lose 0.2mm3 of volume before it snaps back. If the disk has a top surface area of 120mm2 and completely fits under the hammer’s striking face, what is the relevant elastic modulus of the metal? Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown

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).
