Centrifugal force principles are also used in common appliances such as clothes dryers and in devices to control motor speeds and accelerate moving machines.Centripetal force causes an object to travel in circular path.This action is caused by the continuous application of forces,which tend to pull the object to the center.In other words,the inward force,which resists the centrifugal force,is called the centripetal force.The centripetal force of objects spinning at a constant rate produces an acceleration toward the center which is equal and opposite to the centrifugal force.The materials used in the construction of rapidly moving machine parts and mechanisms must be structurally strong enough to provide the centripetal force required to hold the parts to a circular path.At the same time,the materials must be able to withstand the centrifugal force,which tends to pull the parts apart.Motion and the basic laws,which affect motion,are important considerations because of the nume
