Safe Working Load Formula (SWL)

The breaking strain of a nylon line is rated at 15,000 kgs. Using a safety factor of 5, what is the safe working load (SWL)?

SOLUTION:

Safe working load (SWL) is equal to the quotient of breaking strength divided by the safety factor.

This is the Safe Working Load formula:

SWL = BREAKING STRENGTH ÷ SAFETY FACTOR
SWL = 15,000 kgs ÷ 5
SWL = 3,000 kgs
