Sales Online· I have been asked to find the moment of inertia of a rolling ball. The ball can be any size and radius. I have chosen a solid ball. The experiment says that I should roll the ball down a ramp and then measure the time it takes for the ball to roll from the end of the ramp to some fixed distance.

Sales Online2020-11-6 · For instance, for a golf ball you’re whirling around on a string, the moment of inertia depends on the radius of the circle the ball is spinning in: I = mr 2. Here, r is the radius of the circle, from the center of rotation to the point at which all the mass of the golf ball is concentrated.

Sales OnlineInertia, or more specifically, inertia ratio, is one of the most important factors in sizing a servo system. Inertia is defined an object’s resistance to change in velocity, and in servo-driven systems, it can be used as a measure of how well the motor is able to control the acceleration and deceleration of the load.

Sales OnlineThe 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. The moment of inertia of any body having a shape that ...
