Force Measurement
Force, Torque and Shaft Power Measurement
Basic Methods of Force Measurement
1 Balance it against the known gravitational force
2 Measure the acceleration of the body of known mass to which the unknown force is applied
3 Balancing it against a magnetic force
4 Transducing the force to a fluid pressure and the measuring the pressure
5 Applying the force to some elastic member and measuring the resulting deflection
6 Measuring the change in procession of a gyroscope caused by an applied torque related to the measured force
7 Measuring the change in natural frequency of a wire tensioned by the force
