In summary, a gyroscope is a spinning wheel or disc that is used to measure and maintain orientation and angular velocity. It works based on the principle of angular momentum and has a wide range of applications in navigation, aerospace, robotics, consumer electronics, and scientific research. Its advantages include high precision, stability, and reliability, while its limitations include susceptibility to external forces and the need for calibration and maintenance.

What they're talking about here is the case where the wheel is not spinning. So it isn't spinning around the x-axis at all. The gyroscope is initially pointed along the x-axis. If you let go of it, it just falls over, staying in the x-z plane. Since the foot of the gyro is fixed at the pivot, that means the whole gyro is rotating about the y-axis.

Thank you that clears it up a lot
FAQ: Gyroscope Question - Textbook wording
1. What is a gyroscope?
A gyroscope is a device that consists of a spinning wheel or disc mounted on a set of gimbals so that its axis can turn freely in any direction. It is used to measure or maintain orientation and angular velocity.
2. How does a gyroscope work?
A gyroscope works by utilizing the principle of angular momentum. When the wheel or disc spins, it maintains its axis in the same direction due to its inertia. This allows the gyroscope to resist changes in its orientation and maintain a stable position.
3. What are the applications of a gyroscope?
Gyroscopes have a wide range of applications, including navigation and guidance systems in airplanes, ships, and spacecraft. They are also used in smartphones, cameras, and other electronic devices for image stabilization and motion sensing.
4. How accurate is a gyroscope?
The accuracy of a gyroscope depends on various factors such as the quality of the materials used, the precision of its construction, and external factors like temperature and vibration. Generally, gyroscopes used in navigation systems have a high level of accuracy.
5. Can a gyroscope ever lose its orientation?
Yes, a gyroscope can lose its orientation due to external forces such as friction, air resistance, and gravitational pull. However, gyroscopes are designed to minimize these effects and maintain their orientation as much as possible.
