WebRotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. Indeed, the rotational inertia of an object ... WebMar 14, 2024 · $\begingroup$ Note that a flywheel precessing under gravity is a bit of a dangerous system to actually extract energy from. In order for it to precess under gravity, the flywheel must be basically free; if you extract energy by slowing down the flywheel, without also moving it back toward the center of precession, there's a good chance you'll … WebFrom the force given in equation 2 and the area in equation 1 the pressure exerted on the burst liner wall can be calculated.
