Gram inches balance vibration
WebBalance is a zero quantity. Only amount of unbalance can be measured. Unbalance is measured in ounce-inches or gram-inches. Amount of unbalance is a mass (weight) multiplied by its distance from the rotational axis. An unbalance of 100 ounce-inches can be caused by10 ounces at 10 inch radius or 20 ounces at 5 inch radius.
