1. A large and powerful industrial fan has an imbalance in its blades. The blades' center-of-mass (COM) is 0.25m from the axis of rotation. a) Using normal and tangential components, find the COM's magnitude of acceleration when its rotating at a constant speed of 10m/s. b) The COM suddenly accelerates tangentially at a rate of 80m/s². Using normal and tangential components, find the magnitude of acceleration at this moment. c) Answer b) again using polar components. Note, Ö at r case). Also, = ט V r 0.25 m = where r is radius (distance between axis of rotation and COM in this Rotor geometrical center Center of mass d) Given its easier to measure angular velocity and angular acceleration in such scenarios, would you prefer to use polar or tangent and normal components to solve these problems? Why? No wrong answer if you can justify it. e) If you knew the mass of the fan, how would knowing the COM's acceleration be useful?
