All records from the measurement of forces acting on strain gauges and pressures in the hydraulic circuits were then processed through the bus to the measuring control panel and then to the computer, where all values were written and subsequently processed. The measurement was performed at a constant force of 100 kN from the central load cylinder and a force of 70 kN from the side load cylinders (A ÷ D), which had the task of deflecting the upper ground plate that correspond to the real operational load. Within this experimental test, the levers with three basic variants of contact pairs (see Fig. 2) were measured in horizontal and vertical positions. The examples of force measurement records under the segments in the individual quadrants of the bearing for the contact pair Cylinder/Cylinder are shown in Fig. 6.
