This phenomenon gives its name to a device usually consisting of a tube of viscous fluid inside of which is a mass on a spring, and which is often used on dual spin spacecraft.
This phenomenon gives its name to a device usually consisting of a tube of viscous fluid inside of which is a mass on a spring, and which is often used on dual spin spacecraft. Thatdevice is a "damper" named for this phenomenon and is often used as a passive means for energy dissipation. One instance of this phenomenon is usually divided into longitudinal and oblique components, depending on whether its components are parallel or perpendicular to the ecliptic. That astronomical instance of this motion was first noticed by James Bradley in the 18th century, who determined that it has a period of 18.6 years. Because the Earth is not entirely solid, Seth Carlo Chandler observed a non-zero value for the angle of this movement for Earth. Precession, spin and this motion can be modeled with Euler Angles. For 10 points, name this slight "nodding," or "wobble," of an axis of rotation.
