Chapter 1: Q29DQ (page 328)

A gyroscope is precessing as in Fig. 10.32. What happens if you gently add some weight to the end of the flywheel axis farthest from the pivot?

Short Answer

Expert verified

The spinning gyroscope will precess more rapidly.

Step by step solution

01

Formula used

Precession angular speed is

惟=wrlwwhere,

w is weight of the flywheel

r is distance from the pivot

I is moment of intertia and

蝇angular speed.

02

Explanation

Since precessing speed is directly proportional to weight, so as weight will increase, precession angular speed will increase.

So it will precess more rapidly.
