Question

Write any two factors on which the moment of inertia of a rigid body depends

Answer 1

Answer:-

• Moment of inertia of a body depends on the body's mass distribution and the axis of rotation.
• The moment of inertia of a body is directly proportional to its mass and increases as the mass is moved further from the axis of rotation.
• Hence, moment of inertia of rigid body depends upon Mass & Distance from rotating axis.

i hope it helps you.

Answer 2

"The moment of inertia is a quantitative measure of the rotational inertia of a body."

• The opposition that the body shows of having its speed of rotation around an axis differentiated by the application of torque (turning force) is the moment of inertia.
• The axis can be internal or external and could be fixed.
• The moment of inertia is always specified to that axis and is known as the sum of the products obtained by multiplying the mass of each particle of matter in a body by the square of its distance from the axis.

The moment of inertia of a body depends on the factors listed below:

1. Mass of the body.
2. Size and shape of the body.
3. Distribution of mass about the axis of rotation.
4. Position and orientation of the axis of rotation to the body.
