What's the formula for calculating WLL (Working Load Limit)?

  1. Height/Length x WLL x #of slings

  2. WLL/Height x Length

  3. Length/Height x WLL

  4. WLL - Height/Length

The correct answer is: Height/Length x WLL x #of slings

Calculating WLL (Working Load Limit) involves multiplying the Height/Length by WLL and then multiplying that value by the number of slings being used. Option B is incorrect because it divides the WLL by the Height and multiplies that value by the Length, which does not yield the correct calculation for WLL. Option C is incorrect because it divides the Length by the Height, which does not yield the correct calculation for WLL. Option D is incorrect because it subtracts the Height/Length from the WLL, which also does not yield the correct calculation for WLL. Therefore, the correct formula for calculating WLL is option A.
