What is active and reactive gyroscopic couple?
The resisting couple/ reactive couple will act in the direction opposite to that of the gyroscopic couple. This means that, whenever the axis of spin changes its direction, a gyroscopic couple is applied to it through the bearing which supports the spinning axis.
What is meant by gyroscopic torque?
A gyroscopic torque will result if the axis of the flywheel is rotated and it acts perpendicular to the rotor axis. The magnitude of the torque is the product of the flywheel rotor moment of inertia, the flywheel angular velocity and the angular velocity of the flywheel axis.
What is active gyroscope?
The active gyroscopic torque in gyroscope about a horizontal axis represents. the torque required to cause the axis of spin to precess in the horizontal plane. the force required to cause the axis of spin to precess in the horizontal plane.
What is the effect of reactive gyroscopic?
According to the gyroscopic effect, if we cover axis of spin (ox in this case) with right hand as the curved fingers indicate the direction of rotating propeller and rotate that axis in the direction of the aeroplane is taking turn, then the curved fingers show the direction of active gyroscopic couple and the …
What is spin precession and gyroscopic plane?
Spin Plane: The plane in which the wheel is intended to rotate is called spin plane. In the above figure, precession axis is along X axis and hence precession plane is the Y-Z plane. Gyroscopic plane: Wheel gives an unintentional rotation when it is made to precess. This effect is called gyroscopic effect.
Who uses a gyroscope?
Gyroscopes are used in compasses and automatic pilots on ships and aircraft, in the steering mechanisms of torpedoes, and in the inertial guidance systems installed in space launch vehicles, ballistic missiles, and orbiting satellites.
Where do we use gyroscope?
What is gyroscope and its application?
A gyroscope (from Ancient Greek γῦρος gûros, “circle” and σκοπέω skopéō, “to look”) is a device used for measuring or maintaining orientation and angular velocity. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Telescope, or inside the steel hull of a submerged submarine.
What are the two types of precession?
In physics, there are two types of precession: torque-free and torque-induced. In astronomy, precession refers to any of several slow changes in an astronomical body’s rotational or orbital parameters.
What is reactive gyroscopic couple/torque vector?
The reactive gyroscopic couple/torque vector is taken opposite to active gyro vector direction Gyroscope is used for stabilization and directional control of a ship sailing in the rough sea. A ship, while navigating in the rough sea, may experience the following three different types of motion:
What is active gyroscopic torque in a rotating disc?
It is due to the application of centripetal force. Similar to this a couple is needed to be applied on the axis of spin where the disc is rotating. This is called active gyroscopic torque. Reactive gyroscopic torque- Similarly when a body is rotating centrifugal force acts opposite to that of centripetal force.
What is the gyroscopic effect of motion?
When a part of a body rotates about an axis (called as axis of spin) and if that axis (axis of spin) is made to rotate about any other axis which is called as axis of precession , then a gyroscopic couple come into force which helps the body to rotate about the axis of precession.

What is the formula for output axis of gyroscopic torque?
The output axis is the axis orthogonal to the plane {→n, →w} on which the gyroscopic torque →M = ˙→H acting on the spacecraft is generated. The expression of the gyroscopic torque is (9.159) →M = d(H→w) dt = H˙→w = H˙θ→n × →w.
