The circuit consists of 4 active WSGs. Two are under compression and the others under equal tension.
The strain gauges under tension are positioned in opposite bridge arms. The sensitivity to the moment of
bending is increased. At the same time, longitudinal force, torque and temperature are compensated.
The strain is computed as:
