Theory of Tungsten Alloy Crankshaft Counterweight

It is generally knows to all that a rotating object will generate centripetal force which is an actual force or load generated perpendicular to the direction of rotation. In fact, the magnitude of the force increases exponentially with speed. Increase the speed, the force will expand to four times or more of the speed. The amount of imbalance and distance from the axis of rotation greatly influence the centripetal force created by a tungsten alloy crankshaft imbalance .As long as the amount of centripetal force is offset by an equal force in the opposite direction, an object will rotate with no vibration. For instance,tie a brick on each end of a yardstick and you can twirl it like a baton because the weight of one brick balances the other. If we’re talking about a flywheel, the flywheel will spin without wobbling as long as the weight is evenly distributed about the circumference. A heavy spot at any one point, however, will create a vibration because there’s no offsetting weight to balance out the centripetal force.
