When an object rotating about an axis is applied with external torque along a direction perpendicular to the rotational axis, the precession occurs. When the gyroscope is applied with external torques or rotations about the given axis, the orientation can be measured by a precession phenomenon. It acquires extraordinary stability of balance at high speeds as it maintains the high speed rotation axis of its central rotor. The rotor possesses three degrees of rotational freedom and spins about an axis. The axle of the spinning wheel defines the spin axis.

The gimbals consist of frictionless bearings that isolate the central rotor from outside torques. The gyroscope is a massive rotor that is fixed in light supporting rings called gimbals. Each component exploits some physical property of the system enabling it to detect rotational velocity about some axis. The gyroscope has evolved from technology such as mechanical-inertial spinning devices including gimbals, axles, rotors and other electronic and optical devices. However, the orientation changes in response to an external torque and in a different direction. For more information, consult any college physics text on the subject of precession.A gyroscope is a device designed to have a spinning disc or wheel mounted on a base such that its axis can turn freely in one or more directions in order to maintain its orientation regardless of any movement of the base. However, the effect itself is well worth experiencing, even though its explanation is too difficult to undertake here. Unfortunately, the gyroscopic precession of the wheel hanging from the rope is not explainable in as straightforward a manner as the rotating stool effect. The system as a whole ends up obeying the principle of conservation of angular momentum. The change your angular momentum compensates for the change in angular momentum of the wheel. If you are sitting on a low-friction pivot, the twisting force of the bicycle wheel will cause you to turn. (That’s because for every action there is an equal and opposite reaction.) Thus, when you twist the bicycle wheel in space, the bicycle wheel will twist you the opposite way. The bicycle wheel will then exert an equal and opposite torque on you. To do this, you must exert a twisting force, called a torque, on the wheel. One way to change the angular momentum of the bicycle wheel is to change its direction. Suppose you are now sitting on the stool with the bicycle wheel spinning. This means that any change in angular momentum within the system must be accompanied by an equal and opposite change, so the net effect is zero. The bicycle wheel, you, and the chair form a system that obeys the principle of conservation of angular momentum. Angular momentum is characterized by both size and direction. For example, most of a bicycle wheel’s mass is concentrated along the wheel’s rim, rather than at the center, and this causes a larger angular momentum at a given speed.

A rotating bicycle wheel has angular momentum, which is a property involving the speed of rotation, the mass of the wheel, and how the mass is distributed.
