What is the SWL of a rope that has a CBS of 1445 and a DF of 5?

The main idea is that the safe working load (SWL) is found by dividing the rope’s breaking strength by its design factor. Here, the breaking strength (CBS) is 1445, and the design factor (DF) is 5. So SWL = 1445 ÷ 5 = 289. This shows that with a 5:1 safety margin, the rope should be used at up to 289 units of load (pounds in this context). The other numbers would come from multiplying by DF or dividing by a different factor, but with a DF of 5, 289 is the correct SWL.
