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).

Question

2. A human biceps(upper arm muscle)
may exert a force of the order of 600N
(about 135 Ib) on the bones to which it
is attached. If the muscle has a cross-
sectional area at its center of 50
cm^2=0.0050 m^2, and the tendon
attaching its lower end to the bones
below the elbow joint has a cross
section of 0.50 cm^2=5.0x10^-5 m^2,
find the tensile stress in each of these
cross sections.
