Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Many rotating mechanical components can be modeled as a disk with a hole as shown below. Examples include pulleys, gears, bearings, rollers, sprockets, tires, and wheels. Determine the general solution for mass moment of inertia of a disk with a hole as a function of mass (m), outer diameter (D), inner diameter (d), and width (w). Although your solution must not include density, it may be helpful to find density as an intermediate equation. D m:mass
