2 Safety brake on saw blade A table saw has a circular spinning blade with moment of inertia 1 (including the shaft and mechanism) and is rotating at angular velocity wo. Some newer saws have a system for detecting if a person has touched the blade and have brake mechanism. The brake applies a frictional force tangent to the rotation, at a distance from the axes. 1. How much frictional force must the brake apply to stop the blade in time t? (Answer in terms of I, w, and T.) 2. Through what angle will the blade rotate while coming to a stop? Give your answer in degrees. 2 of 4
