Gyroscopic effect: discussions

zaveri · 2012-07-25T03:22:24+00:00

I hope most of you know about the gyroscopic effect: If a rotor rotates about any of the co-ordinate axis,(say x-axis) and if a torque is applied on it along another co-ordinate axis(say y-axis), then the rotor starts rotating along the third co-ordinate axis as well(the z-axis). here the x-axis is called the axis of rotation , while the y-axis is the axis of precision. Now the general idea behind the gyroscopic effect is that a rotating element either rotates about one or all the three mutually perpendicular axes. Now consider, that a brake drum attached to a motor spindle is at rest. the spindle axis is the axis of rotation. now the rotor is made to rotate along the other two mutually perpendicular axes, then would there be rotation along the spindle axis ?

Only if the axis of rotation is tilted , gyroscopic couple comes into play.

Are you sure? This action cannot be undone.

The principle is just that the axis of rotation of a rotating object, whether a galaxy, star, planet or a humble top is invariant in space. If a force acts on the axis of rotation in any direction other than along the axis (not necessarily at right angles) the object precesses in a resultant direction.

Are you sure? This action cannot be undone.
