The motor runs at constant speed and produces a 15-N force at 200 cycles/min because of a small unbalance in the motor. The resulting force vibration was not detected until after the saw had been manufactured. The manufacturer wants a vibration absorber designed to drive the table oscillation to zero simply by retrofitting an absorber onto the base.
