A flywheel is a solid, rotating disk that is sometimes used to store energy. The moment of inertia for a solid disk is 1/2MR^2 where M is the mass and R is the radius. If a flywheel weighs 15kg and has a radius of 0.8m, determine the following. A) If a point on the outside of the disk is moving at 6 m/s, what is the angular velocity of the flywheel? B) If the flywheel starts from rest...
A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 159-mile trip in a typical midsize car produces about 1.53 x 109 J of energy. How fast would a 14.3-kg flywheel with a radius of 0.203 m...
