[Balance] Principles of Imbalance Forces and Moments - Centrifugal Force
Centrifugal Force
When a mass (m) is rotated around an axis at radius ( r) and angular velocity (w), it exerts a centrifugal force ( F) in the radial direction.
Newton’s Law:
Units are: Imbalance is (mr), with units of mass times distance In the case of a TWA, imbalance (mr) is unknown, so the centrifugal force (F) and angular velocity (w) must first be measured to determine (mr). The machine must accurately and repeatedly measure (F).
