gyroscopic couple. This developed gyroscopic couple generates a higher force on the bearings, which in turn leads to accelerated bearing wear. Because of a higher rate of wear, the bearings face earlier failure as compared to the projected life of the bearings in ideal conditions. Use of An aeroplane loops the loop in a verticle circle of radius 200m, with a speed of 40m/s at the top of thel oop. The pilot has a mass of 80kg. What is the tension in the strap holding him into his seat when he is at the top of the loop?. The centrifugal force outwards due to the rotation is mv^2/r = 80*40^2/200 = 640N The gyroscope precesses around a vertical axis, since the torque is always horizontal and perpendicular to L. If the gyroscope is not spinning, it acquires angular momentum in the direction of the torque ( L = ΔL ), and it rotates around a horizontal axis, falling over just as we would expect.

NPR COLLEGE OF ENGINEERING & TECHNOLOGY Subject : DYNAMICS OF MACHINERY M.Mathan Raj Assistant Professor / Mech NPRCET The reactive gyroscopic couple of the same magnitude will act in the opposite direction (i.e. in anticlockwise direction). The effect of this reactive gyroscopic couple is to raise the bow and lower the stern. When the ship steers to the right under similar conditions as discussed, the effect of the reactive gyroscopic couple will be to raise. Rotating shafts tend to bow out at certain speeds and whirl in a complicated manner. Whirling is defined as the rotation of the plane made by the bent shaft and the line of centers of the bearings. The phenomenon results from such various causes as mass unbalance, hysteresis damping in the shaft, gyroscopic forces, and fluid friction in bearings A gyroscopic apparatus (100), having application as a prime mover, comprises a pair of discs (102) disposed opposite one another with arms (104) rotatably supporting the discs (102) connected at a pivot point, the pivot axis thereof lying in a plane midway between the discs (102).
