Precession angular speed is

$\mathrm{Î\copyright }=\frac{wr}{lw}$where,

w is the weight of the flywheel

r is the distance from the pivot to the center of gravity

I is moment of inertia and

$\mathrm{Ó\neg }$angular speed.

From the formula, it is clear that precession angular speed$\mathrm{Î\copyright }$is inversely proportional to the angular speed $\mathrm{Ó\neg }$.

So if $\mathrm{Ó\neg }$is doubled, $\mathrm{Î\copyright }$will be halved.

Hence, precession angular speed$\mathrm{Î\copyright }$will be cut in half.

From the formula, it is clear that precession angular speed $\mathrm{Î\copyright }$ is directly proportional to weight w.

So if w is doubled$\mathrm{Î\copyright }$, will also be doubled l.

Hence, precession angular speed$\mathrm{Î\copyright }$will be doubled.

From the formula, it is clear that precession angular speed $\mathrm{Î\copyright }$ is inversely proportional to the moment of inertia I.

So if I is doubled $\mathrm{Î\copyright }$, will be halved.

Hence, precession angular speed$\mathrm{Î\copyright }$ will be cut in half.

From the formula, it is clear that precession angular speed$\mathrm{Î\copyright }$ is directly proportional to the distance from the pivot to the centre of gravity r.

So if r is doubled,$\mathrm{Î\copyright }$ will also be doubled.

Hence, precession angular speed$\mathrm{Î\copyright }$ will be doubled.

If all four factors are doubled, the total effect will be balanced and precession angular speed$\mathrm{Î\copyright }$ remains the same.
