Problem 55E

A gyroscope is precessing about a vertical axis. Describe what happens to the precession angular speed if the following changes in the variables are made, with all other variables remaining the same: (a) the angular speed of the spinning flywheel is doubled; (b) the total weight is doubled; (c) the moment of inertia about the axis of the spinning flywheel is doubled; (d) the distance from the pivot to the center of gravity is doubled. (e) What happens if all four of the variables in parts (a) through (d) are doubled?

Step-by-Step Solution:

Solution 55E Introduction We have to discuss how the precession changes if the given parameter changes. Step 1 The angular velocity of precession is given by Here I is the moment of inertia of the gyroscope about its axis, and is the angular speed of spin, r is the distance or center of mass from the pivot and w is the weight. (a) From the above equation we can see that the precession speed inversely proportional to the angular speed of spin. Hence if the angular speed of spin is doubled the angular speed of precision will be halved. (b) From the equation (1) we can see that the precession is directly proportional to the weight of the gyroscope, hence if the weight...
