Flywheel equations
WebMoment of inertia of a flywheel is calculated using the given formula; I = N m N + n ( 2 g h ω 2 − r 2) Where I = moment of inertia of the flywheel.Here, the symbols denote; m = rings’ mass. N = flywheel rotation. n = number of windings of the string. h = height of the weight assembly. g = acceleration due to gravity. WebThus we will determine if a flywheel of similar mass can store energy equivalent to this battery. The following equations can be found in most physics textbooks and flywheel …
