See Fig. P8–32. Determine the radius of gyration of the built-up section shown with respect to the horizontal centroidal axis. The dashed line at the bottom of the section represents lacings for connecting the component parts at the open side. The areas of the lacings are not considered as effec- tive areas when calculating the moment of inertia.

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.
