TORQUETRAK CALCULATORS

Use these calculators to determine the torque strain or shunt resistance on a solid or hollow shaft.

The Torque Strain Calculator determines the amount of strain expected on a shaft surface due to an applied torque. Use the microstrain level to determine the appropriate gain needed for a strain-gage based telemetry system.

The Shunt Resistance calculator correlates a resistance to a simulated strain level for a given strain gage. It provides a simple way to calculate how large of a resistor to place on an arm of a strain gage sensor in order to simulate a desired strain. For more information on shunt calibration of a strain-gage based telemetry system, see page 33 of the TorqueTrak 10K users guide.

Please note: equations are dependent on units and listed below. Use the calculator that corresponds to your desired units of measurement.  Note that for a solid steel shaft, yielding is likely to occur above 500 microstrain.
