WebFeb 18, 2024 · $\because$ Flywheel Energy Storage One way to store energy is in the rotational motion of a flywheel, and some have proposed using such technology to power automobiles. One unit is based on a $6.0-\mathrm{kg}$ flywheel in the shape of a hoop of radius 0.10 $\mathrm{m}$ that spins as fast as $60,000$ rpm.
Webω = Angular velocity of flywheel in rad.s-1, v = Liner velocity at the mean radius in ms-1, σ = Tensile stress or hoop stress in m, fConsider a small element of rim as shown in fig. Let it subtend. an angle δƟ at the centre of the flywheel. Volume of the small element = A*RδƟ. Therefore, mass of the small element, china buffet greenfield maWebSo the speed of the center of mass is equal to r times the angular speed about that center of mass, and this is important.
