Question

Define Moment of Inertia?​

Answer 1

☯ AnSwEr :

• A measure of the resistance of a body to angular acceleration about a given axis that is equal to the sum of the products.

• The moment of inertia is a physical quantity which describes how easily a body can be rotated about a given axis.

• moment of inertia is that property where matter resists change in its state of rotatory motion.

• The larger the moment of inertia, the greater the amount of torque that will be required to bring the same change in its angular velocity in a given amount of time.

• S.I unit of moment in inertia is kg m².

• Dimensional formula of moment of inertia is $\Large{\sf{ \bigg[M^{1} L^{2} T^{0} \bigg]}}$

Answer 2

Moment of inertiais the mass property of a rigidbodythat defines the torque needed for a desiredangular accelerationabout an axis of rotation. Moment of inertia depends on the shape of the body and may be different around different axes of rotation.
