Frequently Asked Questions

Q1: What are the three basic Newton’s laws of motion?

A1: Three basic newton’s laws of motion are,

  • Law 1 states that “A body does not change its state of motion unless acted upon by a force”
  • Law 2 states that “A force of magnitude F applied on a particle gives it an acceleration a proportional to the force”
  • Law 3 states that ” For every action there is a equal and opposite reaction”

Q2: What is rigid body mechanics?

A2: Study of mechanics of deform able bodies and fluid mechanics’s basic requirement is rigid body mechanics. It iver very much required for the design, analysis of structural members, electrical devices, mechanical components, encountered in the field of engineering. It does not deform under load. Statics under rigid body mechanics deals with the body equilibrium under action of forces even when the body is either at rest or moving with the constant velocity. Dynamics under rigid body mechanics deals with the motion of bodies.

Q3: What is concentrated force?

A3: Concentrated force is an effect of a loading which is assumed to act at a point on a body provided the area over which load is applied is small compared to the overall size of the body. For example, contact force between ground and a wheel.
