Jump shot parameters selected to determine movement pattern included kinematic analysis of a number of variables around the ankle, knee, hip, trunk, shoulder, elbow, and wrist joints and the following variables determined: (a) temporal series of joint angular displacement and velocities; (b) minimum and maximum joint angular displacements; (c) joint range of motion (d) joint angle at ball release; (e) minimum and maximum joint angular velocities; and, (f) movement duration.
Its volumetric efficiency used most in the field to determine the condition of a hydraulic pump - based on its increase in internal leakage through wear or damage. But without reference to theoretical flow, the actual flow measured by the flow meter would be meaningless.
Mechanical efficiency. Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one. For simple machines, such as the lever and the jackscrew, the efficiency is the actual load lifted divided by the theoretical force delivered.
