The ratio of the tensile (or compressive) strength to the density of a material is  a measure of how strong the material is "pound for pound." What is the strength of tendon (tensile strength 79.0 MPa, density 1100 kg/m^3)?        What is the strength of steel (tensil strength 0.570 GPa, density 7700 kg/m^3)? What is the strength of bone (compressive strength 159 MPa, density 1590 kg/m^3)? What is the strength of concrete (compressive strength 0.410 GPa, density 2700 kg/m^3)?

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).
