Re: Measuring rotating shaft torque. A linear rotating shaft supported on bearings can be considered the simplest element in a drive system, however their static and dynamic characteristics need to be considered. T = F * L; F= force (lbs) and L= perpendicular distance of the force area. Commercial solutions (sensors, antennas and interrogation unit) can easily … To measure the nearly static, steady state torque that drives the wheels, an inline torque sensor could be placed between the rim and the hub of the vehicle, or in the drive shaft. Here a bridge consisting of four strain gauges is utilized, the bridge eliminating the effect of bending which usually occur in a shaft. No. This will be driven by an IC engine of ~100 hp, operating near 4,000 RPM for a torque in the neighborhood of 150 lb-ft. In general.
