Because the size of the torsion bar of the experiment table
was designed as 2 meters, and was placed bilaterally
symmetrically with the axis of the steel shaft, the maximum
value of the arm of force was 0.95m, and when the suspender
mass was increased to 10.32kg the torque input in was
100.09N.m; and when the suspender mass was further
increased, the suspender mass was increased features of the
measuring system were shown such as shaking and unstable
indication, so the maximum value YF.S of the system was
lOON.m. take the first line of Table 1 as an example, when the
torque of 43.62 N-m was input in the measuring system, the
repeatability of the group of experiment data acquired was
