Question

What are the common forces in mechanics?

Answer 1

You will encounter a wide spectrum of forces when studying mechanics. Contact and non-contact forces are the two types of forces that can be found.The gravitational force, as well as electrical and magnetic forces between charged and magnetic things, are examples of non-contact forces.

Complete answer:
Contact force: When one object collides with another, a contact force is created. Mutual contact forces exist whenever two objects come into contact with each other, and they satisfy Newton's Third Law of Motion. Normal Reaction is the component of the contact force that is normal to the contact surfaces. Friction is the term for the component that runs parallel to the surfaces.

Gravitational force: The attraction between any two bodies is proportional to the product of their masses and inversely proportional to the square of their distance. This is the statement of the concept of force of gravitation.

Spring force: Spring is a tool that many of us use on a daily basis, and their inertia is sometimes overlooked since it is assumed to be massless. When a spring is strained, it undergoes displacement; when it is compacted, it becomes compressed; and when it is free, it returns to its equilibrium position. Spring exerts an equal and opposite force on a body that compresses or extends it, according to this fact.

Force of tension: Tension force is the force produced when a load is applied in a direction away from one or more ends of a material, usually to the cross-section of the material. Tension is frequently described as a "pulling" force. To be a tension force, the load supplied to the material must be exerted axially.

Note: Friction is a negative force that opposes relative motion and dissipates energy in the form of heat in devices with several moving parts. Friction, on the other hand, is extremely significant in our daily life. The friction between our feet and the earth allows us to walk.
