A miter saw has an operating speed of 1500 rpm (157.08 rad/s). The blade and motor armature have a combined weight of 3 lbs and a radius of 1 inch. I = mr2 (Impulse and Momentum) - What is the time required for the bearing friction (torque =.015 in lbs) alone to stop the blade? - What is the torque a braking system would need to apply to stop the blade in just .25 seconds?
