    A steel tube, 24mm OD and 20mm ID is used to create a torque sensor. Four gauges are fitted to the tube in a bridge configuration and the bridge is supplied from a 10V source.

    Gauge Factor = 2.125
    Shear modulus for steel = 82GN/m^2
    Young modulus for steel = 210 GN/m^2
    Max shear strain = 1000x10^-6

    What is the output voltage from the bridge if the applied torque is 50Nm?
