Question

How does force change the shape of an object?

Answer 1

The change in the shape of the body is the measure of the body's strength that can be defined as the measure of strain generated in any part of the body when stress is applied. The bodies that make a great deal of change in shape. It can be said to be made from low-density material to the extent of applying some force, while it can be said that the one that retains its shape the most after applying some force is made from highly dense material.

Complete solution:
In the practical world, the application of force changes the shape of every object. In the application of forces, even metals or steel bars alter their shape. The difference is the degree of shape deformation in the application of forces. Change in shape is so less in solids, for example, that it becomes difficult to observe it so we call it negligible change. Whereas in the case of fluids (fluids mean both gases and liquids), the shape of the body can be continuously altered by the smallest possible force until the force is removed. Some examples of forces of this kind are:
1.Compression force, which tends to reduce the length of a rod.
2.The expansion force that tends to elongate springs, rubber bands,
3.The shear force tends to convert a cube made of rubber to a parallelogram.

Note:
All these forces, when applied in a certain direction to a certain material, have their own properties. Not only the amount of force applied, but also the direction of application and the material on which force is applied depends on the deformation.
