SUMMARY
The moment of a spinning wheel can be calculated using the formula T = I * a, where T represents torque, I is the moment of inertia, and a is angular acceleration. For a wheel with a radius of 1 m, height of 5 cm, and mass of 1000 kg, the moment of inertia Iz is calculated using Iz = (1/2)mr², which is appropriate for standard applications such as automotive wheels. The alternative formula Ix = Iy = (m/12) * 3r² + h² is applicable for different axes of rotation but is not necessary for typical wheel scenarios.
