The effective mass whose inertia transforms an acceleration along or about an input axis into a force or torque. The effective mass takes into consideration flotation and contributing parts of the suspension. 2, record 1, English, - proof%20mass
Record number: 1, Textual support number: 1 CONT
The function of an accelerometer is to measure specific forces acting on the vehicle, and hence changes in vehicle direction and position, within the gyro-stabilized frame of reference. Most acceleration measuring devices in use today employ the inertia reaction of a proof mass. The proof mass is manifested as pendulous unbalance, and is generally supported by flotation. 3, record 1, English, - proof%20mass
