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.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
