Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Can you please answer number 3

1. Determine the moment of inertia of a 4-kg disk with 12-cm radius.
2. Determine the moment of inertia of a 4-kg ring with a 10-cm inner radius and a 12-cm outer
radius.
Notice that even though both objects have the same mass and the same outer radius, they have
different moments of inertia because their shapes are different! The ring will resist more when we try to
change its angular velocity than the disk will.
