Which components make up a gyroscope?

A gyroscope is an instrument that measures or maintains orientation based on the principles of angular momentum. The components that make up a gyroscope include a rotor, gimbal rings, and a support mount.

The rotor is the spinning mass that provides the gyroscope with stability and angular momentum. This spinning action allows the gyroscope to resist changes in its orientation. The gimbal rings are a set of rings that allow the rotor to remain stable while being able to pivot freely in multiple directions. This design enables the gyroscope to maintain its orientation regardless of the movement of the surface or frame to which it is attached. The support mount is the structure that holds the gimbal rings and rotor in place, providing stability and support for the entire unit.

Understanding these components is crucial for comprehending how gyroscopic instruments function in various applications, from navigation systems in aircraft to stabilization systems in smartphones. The other options contain components that do not pertain to the traditional understanding and structure of a gyroscope, making them incorrect choices.
