The Radius of Gyration of a body is defined as the perpendicular distance from the axis of rotation to the point of mass whose mass is equal to the mass of the whole body and the Moment of Inertia is equal to the actual moment of inertia of the object as it has been assumed that total mass of the body is concentrated there. Uniform Plate or Rectangular Parallelepiped This table discusses expressions for the moment of inertia for some symmetric objects along with their rotation axis: I = ∑m i r i 2 Moment Of Inertia Formula for Different Shapes For non-uniform objects, we calculate the moment of inertia by taking the sum of the product of individual point masses at each different radius for this the formula used is.For uniform objects, the moment of inertia is calculated by taking the product of its mass with the square of its distance from the axis of rotation (r 2 ).

Several ways are used to calculate the moment of inertia of any rotating object. Moment of Inertia of any object depends on the following values: I represent moment of inertia of the body about the axis of rotationįrom the equation, we can say that the moment of inertia of a body about a fixed axis is equal to the sum of the product of the mass of each particle of that body and the square of its perpendicular distance from the fixed axis. Now the moment of inertia of the entire body about the axis of rotation AB will be equal to the sum of the moment of inertia of all the particles, so

Moment of inertia of n th particle = m n ×r n 2

Moment of inertia of third particle = m 3 ×r 3 2 Role of Mahatma Gandhi in Freedom Struggle.
