A student performed an experiment to examine the stress-strain properties for two elastic objects and discovered that Object 1 had a Young’s modulus of 600 MPa and Object 2’s modulus was 2300 MPa. A) Which of these objects is stiffer? B) Which of these objects stores more energy when defined by the same amount of stress?

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).
