Define Torque and Moment of the Torque or Couple
There are many examples in practice where two forces, acting together, exert a moment. or turning effect on some object. As a very simple case,…

Explain Moment of Force
A force can rotate a nut when applied by a wrench or it can open a door while the door rotates on its hinges; in…
Theorems of Moment of Inertia
Theorems of Moment of Inertia: (i) Parallel axes theorem: The moment of inertia of a body about any axis is equal to the sum of…
Moment of Inertia and its Physical Significance
Moment of inertia is a determination of how complicated it is to rotate an exacting body about a given axis. It is a measure of…
Equations of Rotational Motion
As in linear motion, for a body having uniform angular acceleration, here derive the equations of motion. Let consider a particle start rotating with angular…
What is Rotational Motion?
When a body rotates about a fixed axis, its motion is known as rotatory motion. A rigid body is said to have pure rotational motion,…
Define Rigid Body in terms of Rotational Motion
A rigid body is defined as that body which does not undergo any change in shape or volume when external forces are applied on it.…
Types of Equilibrium of Bodies
There are three types of equilibrium of bodies. They are: (a) Stable equilibrium (b) Unstable equilibrium (c) Neutral equilibrium Consider three uniform bars shown in…
Explain Equilibrium of Bodies
If a marble M is placed on a curved surface of a bowl S. it rolls down and settles in equilibrium at the lowest point…
