A 360 lb motor is bolted to a light horizontal beam. The unbalance of its rotor is equivalent to a 0.9 oz weight located 7.5 inches from the axis of rotation, and the static deflection of the beam due to the weight of the motor is 0.6 inches. The amplitude of the vibration can be decreased by adding a plate to the base of the motor. If the amplitude of the vibration is to be less than 2.16 × 10 in for motor speeds above 300 rpm, determine the weight of the plate.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
