13. Rotational Inertia & Energy

Parallel Axis Theorem

Physics - Mechanics: Moment of Inertia (1 of 7) Parallel Axis Theorem: Example 1

A thin, rectangular sheet of metal has mass M and sides
of length a and b. Use the parallel-axis theorem to calculate the
moment of inertia of the sheet for an axis that is perpendicular to the
plane of the sheet and that passes through one corner of the sheet.

Parallel Axis Theorem & Moment of Inertia - Physics Practice Problems

29.4 Parallel Axis Theorem

Find the moment of inertia of a hoop (a thin-walled, hollow ring) with mass M and radius R about an axis perpendicular to the hoop’s plane at an edge.

A uniform bar has two small balls glued to its ends. The bar is 2.00 m long and has mass 4.00 kg, while the balls each have mass 0.300 kg and can be treated as point masses. Find the moment of inertia of this combination about an axis (d) parallel to the bar and 0.500 m from it.
