Question

If two circular disks of the weight and thickness are made from metals having different densities. Which disk, if either will have the larger moment of inertia about its central axis.

Answer 1

The moment of inertia formula is I=MR. The formula of moment of inertia changes with the change in the object size.

• There is given that circular disks and we need to find who will have the larger moment of inertia.
• As the moment of inertia depends upon two factors that are radius and mass of the object.
• These two factors are directly proportional to the moment of inertia.
• Out of two circular disks which will have the bigger radius that one will going to have the more moment of inertia.
