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

Required information
The leg bone (femur) breaks under a compressive force of about
5.70 × 104 N for a human and 10.4 × 104 N for a horse. The human
femur has a compressive strength of 160 MPa, whereas the horse
femur has a compressive strength of 140 MPa.
What is the effective cross-sectional area of the femur in a horse? (Note: Since the
center of the femur contains bone marrow, which has essentially no compressive
strength, the effective cross-sectional area is about 80% of the total cross-sectional
area.)
