Write 1 sentence for each defining the meanings of the terms

Write 1 sentence for each defining the meanings of the terms \"forced precession\", \"free precession\", \"nutation\", \'\'gyroscopic moment/force\" and \"stability of torque-free motion of a rigid body\".

Solution

forced precession- the kind of motion of gyroscope subjected to external torque.

free precession-motion of axis of spinning body when subjected to external force

nutation- periodic variation in inclination axis of body sujected to rotation

gyroscopic force-force exerted by gyroscopic body due to resisting to applied couple on it. Rotation of gyroscopic body produces moment about its axis.

Stability of torque free motion of rigid body- rigid body makes its rotation about its principal axis of inertia tensor.
