Abstract: A calibration stand for electrical torque transducers capable of applying torque loads on the order of 300,000 inch-pounds (33,900 newton-meters) has deadweight loading applied through a thin flat high carbon steel hangar strap. The hangar strap contacts the end of the load moment beam on a curved surface having a constant radius of curvature equal to the distance of the surface from the beam torque axis. As the transducer deflects under increasing deadweight loading on the hangar strap, the load moment beam rotates and the strap remains vertical and contacts the loading surface along a moving tangent point which has a precise constant distance from the torque axis for providing a high degree of accuracy.
