FIGURE 1: BWDLING TERMINOLOGY

When supporting a load with two or more bridling lines, the tension in each line is greater than the load divided by the number of lines. This is true because each bridling line pulls against the other(s) in addition to supporting its share of the load. See Figure 1. As the angle between the bridling lines and horizontal decreases, the tension in the lines increases. The table in Figure 2 provides multiplying factors used to determine the tension in each of the bridling lines.

To determine the tension in each bridling line, divide ...
