SWL (Safe Working Load) can be calculated by dividing the breaking strength of a material by a safety factor.

• SWL = Breaking Strength / Safety Factor

• Breaking Strength is the maximum load a material can withstand before failure

• Safety Factor is a multiplier applied to the breaking strength to ensure safety

• Example: If a rope has a breaking strength of 10,000 lbs and a safety factor of 5, SWL = 10,000 / 5 = 2,000 lbs
