This is arguably the most critical daily calculation. As the angle of a sling leg decreases from vertical, the tension on it increases dramatically. The Load Angle Factor (LAF), also called the Tension Factor (TF), is used to quantify this. For example, a 60-degree angle from horizontal has a factor of 1.155. The standard formula for sling tension is:
