WebA bicycle wheel with a radius of 38 cm is given an angular acceleration of 2.61 rad/s^2 by applying a force of 0.45 N on the edge of the wheel. What is the wheel's moment of inertia? Calculate the moment of Inertia for a ring with a mass 0.715 kg, an inner radius of 10.7 cm and an outer radius of 12.7 cm. WebMoment of inertia is a quantity that expresses a body’s tendency to resist angular acceleration about the axis of rotation. It is given as the product of the mass of a rigid body and the square of the distance from the axis of rotation. I = m r 2. cholagol drops uk https://horseghost.com
