A 10-m length of 1.0-mm-radius copper wire is stretched by holding one end fixed and pulling on the other end with a force of 150 N. What is the change of length? By briefly increasing the force to exceed the limit of elastic behavior (a fractional elongation of approximately 1.0%), the wire may be permanently deformed; this is often done in order to straighten out bends or kinks in a wire. Approximately what force is necessary?

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).
