Mass moment of inertia of a wheel
WebThe unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square. In the U.S. customary system, m is in slugs (1 slug = 32.2 pounds) and r in feet, with I expressed in terms of slug-foot square. WebWhere, I = Moment of inertia of the flywheel assembly N = Number of rotation of the flywheel before it stopped m = mass of the rings n = Number of windings of the string on the axle g = Acceleration due to gravity of the environment. h = Height of the weight assembly from the ground. r = Radius of the axle.

WebRotational kinetic energy = ½ moment of inertia * (angular speed) 2. When the angular velocity of a spinning wheel doubles, its kinetic energy increases by a factor of four. When an object has translational as well as rotational motion, we can look at the motion of the center of mass and the motion about the center of mass separately. WebMoment of inertia quantifies the rotational inertia of a rigid body and can be expressed as. I = k m r 2 (2) where. k = inertial constant - depends on the shape of the flywheel. m = …
