We illustrate the precession of a gyroscope with an example of a top in the next two figures. If the top is placed on a flat surface near the surface of Earth at an angle to the vertical and is not spinning, it will fall over, due to the force of gravity producing a torque acting on its center of mass.

If the torque is applied about the z axis, the result will be rotation about the y axis and this is called precession. Figure 4 If the torque is not applied and the rotation is made to happen (applied), a reaction torque will be produced (Newton's 3 rd. law) and the disc will respond to …

Describe the right-hand rule to find the direction of angular velocity, momentum, and torque. Explain the gyroscopic effect. Study how Earth acts like a gigantic gyroscope. Angular momentum is a vector and, therefore, has direction as well as magnitude. Torque affects both the direction and the magnitude of angular momentum.

If when rotating about one axis (axis of spin) a torque is applied about another axis (axis of torque), the body will rotate about the third axis (axis of precession). Use the right hand rule (thumb, first and second finger mutually at right angles), where first finger represents axis of spin, second finger represents axis of torque and thumb ...

Force and torque diagram for the gyroscope The reason that the gyroscope does not fall down is that the vertical component of the contact force exactly balances the gravitational force

Consider an instant in time at which the Eulerian angle is zero. This implies that the -axis is horizontal [see Equation (534)], as shown in the diagram. The gravitational force, which acts at the center of mass, thus exerts a torque in the -direction. Hence, the components of the torque in the body frame are.

The direction of precession depends on the direction of rotation of the wheel with respect to the axle. The spinning wheel is characterised by a torque in the direction of spin. A torque is the measure of the force causing rotation and depends on the actual force used to spin the wheel and the radius of the wheel.
