Another example is problematic interaction with the spacecraft Attitude Control System ( ACS ), especially for spinning satellites which can suffer resonance between slosh and nutation, or adverse changes to the rotational inertia.

A number of wheel manufacturers are now producing wheels with roughly half the spokes of the highest performance traditional wheel from the 1980s, with approximately the same rotational inertia and less total weight.
43.
If the points represent mass, then the zeroth moment is the total mass, the first moment divided by the total mass is the center of mass, and the second moment is the rotational inertia.
44.
By using a transmission gearbox, the rotational inertia of the flywheel can be used to directly start up a diesel engine, and once running, the diesel engine can be used to directly spin the flywheel.
45.
It also can be referred to as the radial distance from a given axis at which the mass of a body could be concentrated without altering the rotational inertia of the body about that axis.
46.
The rotational inertia of the front wheel will lessen the severity of the wheel flop effect because it results in opposing torque being required to initiate or accelerate changing the direction of the front wheel.
47.
By mounting a pair of gyroscopes ( of the same rotational inertia and spinning at the same speed in opposite directions ) at right angles the precessions are cancelled, and the platform will resist twisting.
48.
So we were able to look at the pillarlike shape of the legs, and as the foot came down, realize that inertia doesn't so much go north and south, but it's more of a rotational inertia.
49.
The weapon uses an unusual delayed blowback operation, where during firing the bolt opening is delayed by the rotational inertia of two flywheels, which are driven by a rack and pinion arrangement on the bolt carrier.
50.
:: : : : : The other saving grace for the car is that it has a high moment of rotational inertia-which means that it can't flop back onto the ground or roll over very quickly.
