Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in the figure below to pull it out. -TOT Tree Trunk (a) What force would you have to exert perpendicular to the center of a rope to produce a force of 15,000 N on the car if the angle is 8 = 1.10°? (Enter the magnitude only.) N (b) Real ropes stretch under such forces. What force would be exerted on the car if the angle increases to 7.00° and you still apply the force found in part (a) to its center? (Enter) the magnitude only.)

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).
