What is the meaning of gyroscopic?

What is the meaning of gyroscopic?

noun. an apparatus consisting of a rotating wheel so mounted that its axis can turn freely in certain or all directions, and capable of maintaining the same absolute direction in space in spite of movements of the mountings and surrounding parts: used to maintain equilibrium, determine direction, etc.

What is gyroscopic couple in theory of machine?

Consider a disc spinning with an angular velocity ( ω rad/s ) about the. axis of spin OX, in anticlockwise direction when seen from the front. Since the plane in which the disc is rotating is parallel to the plane YOZ, therefore it is called plane of spinning.

What is the condition for a gyroscopic couple?

When the rotor spins about X-axis with angular velocity ω rad/s and the inner gimbal precesses (rotates) about Y-axis, the spatial mechanism is forced to turn about Z-axis other than its own axis of rotation, and the gyroscopic effect is thus setup.

What is gyroscopic couple and gyroscopic effect show the expression?

Gyroscopic couple (C ): Let w be angular velocity of a disk. Let wp be angular velocity of precession (rotation of axis of spin) Let the axis of spin be rotated by an angle dθ in time dt. L1 = Iw.

What is the gyroscopic effect?

Gyroscopic motion is the tendency of a rotating object to maintain the orientation of its rotation. A rotating object possesses angular momentum and this momentum must be conserved. The object will resist any change in its axis of rotation, as a change in orientation will result in a change in angular momentum.

What is a synonym for gyroscope?

•gyro (noun) spinner, Gyrostat, spinners, gyroscopes, whirligigs.

What is meant by gyroscopic effect?

Gyroscopic effect is ability (tendency) of the rotating body to. maintain a steady direction of its axis of rotation. The gyroscopes. are rotating with respect to the axis of symmetry at high speed. This gives them big kinetic energy.

What is the effect of gyroscopic couple on rolling of ship?

In case of rolling of a ship the axis of precession is always parallel to the axis of spin for all positions. Hence there is no effect of the gyroscopic couple acting on the body of the ship during rolling.

What is the effect of gyroscopic couple on rolling of ship Why?

What do you mean by gyroscopic couple derive a relation for its magnitude?

It mean that both position are lying in the same place i.e.- in the precession plane about axis ‘OY’ Let, I= Mass amount of inertia of the disc about OX inkg−m2W= Angular velocity rad/sec.

What is gyroscopic effect?

Gyroscopic effect is ability (tendency) of the rotating body to maintain a steady direction of its axis of rotation. The gyroscopes are rotating with respect to the axis of symmetry at high speed.

How the gyroscopic couple affect during the change in direction of aircraft?

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 meant by active and reactive gyroscopic couple?

The reactive gyroscopic couple (equal in magnitude of active gyroscopic couple) will. act in the opposite direction (i.e. in the anticlockwise direction) and the effect of this couple is, therefore, to raise the nose and dip the tail of the aeroplane. Nose. Tail. (a) Aeroplane taking left turn.

What does gyroscopic effect?

What are active and reactive couples and their directions?

The gyroscopic couple acts in anticlockwise direction about Y-axis and the reaction couple acts in opposite direction, i.e. in clockwise direction, which tends to move towards right side (Fig.
