The poles were subjected to a cantilever load test (Fig. 4).
The pole specimen rested on two supports. The first support
was located at the butt end, and the second support,
located 3.0 ft (0.9 m) from the butt end, worked as the
fulcrum. The distance to the fulcrum point was chosen to
represent the typical foundation embedment length used in
practice, which is approximately 10% of the overall pole
length plus 1 ft (0.3 m).
