Researchers have found that a gecko’s foot iscovered with hundreds of thousands of small hairs (setae) thatallow it to walk up walls and even across ceilings. A single foot pad,which has an area of 1.0 cm2, can attach to a wall or ceiling with aforce of 11 N. (a) How many 250-g geckos could be suspended fromthe ceiling by a single foot pad? (b) Estimate the force per squarecentimeter that your body exerts on the soles of your shoes, andcompare with the 11 N>cm2 of the sticky gecko foot.

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).
