- The image displays a two-dimensional, solid circular disc oriented horizontally.
- A vertical line passes through the center of the disc, passing through the point labeled \(O\).
- The disc is depicted undergoing rotation, indicated by a curved arrow forming a circle around the central axis.
- A small mass element, denoted by the label \(\delta m\), is shown located on the disc, horizontally offset from the center \(O\).
- A radial line connects the center \(O\) to the position of the mass element \(\delta m\), and this distance is labeled \(r\).
- The context provided suggests that the diagram relates to calculating the moment of inertia of this small element, specifically mentioning \(\delta m r^2\).
