Rigid pole. The load cells measured eight separate forces on the rigid pole. The total load from summing the eight load cells was 247,300 N. The significant loads were contributed by the roof-rail, floor-sill, and middle-point of the driver door. The peak loads from the roof-rail, mid-door, and lower sill were 26,000 N, 67,300 N, and 184,600 N, respectively. Using torque equations, the height of the resultant load was determined to be 570 mm. This corresponds to a point 120 mm above the lower sill height (level 1). The resultant load is shifted toward the lower sill because the truck frame (which hangs below level 1) contributes 75 percent of the peak force (184,600 N of 247,300N). Table 10 summarizes the load cell data. Data plots from the rigid pole load cells are presented in appendix D.
