What describes engagement points on a flywheel?

Engagement points on a flywheel refer to the specific locations where energy is actively transferred during the operation of the flywheel. These points are crucial because they are involved in the dynamic interactions between the flywheel and other components of a machine. As the flywheel rotates, energy is exerted through these engagement points, allowing for the transformation of kinetic energy into useful work. Essentially, they are the interface through which power is transmitted, whether it's to start machinery, smooth out energy delivery, or store energy for later use.

This understanding of engagement points in the context of energy transfer is vital when considering the overall performance and efficiency of machinery that utilizes flywheels, as they directly impact how effectively the flywheel can perform its intended function.
