To determine the working load limit (WLL) of a wire rope given a specific ultimate load (UL) and a safety factor, we can follow these detailed steps:

1. Understand the given values:
- Ultimate Load (UL): This is the maximum load the wire rope can handle before it fails. The given UL is 13,400 lbs.
- Safety Factor: The safety factor provided in the question is 4:1. This means that the working load limit is 1/4th of the ultimate load to ensure safety during usage.

2. Set up the calculation:
- Working Load Limit (WLL) can be calculated by dividing the Ultimate Load (UL) by the safety factor. This ensures that the load used in practical operations is within a safe range.

3. Perform the calculation:
- WLL = UL / Safety Factor
- Plug in the provided values: WLL = 13,400 lbs / 4

4. Simplify the expression and compute the result:
- WLL = 13,400 lbs / 4 = 3,350 lbs

Hence, the working load limit (WLL) of a 3/8" fiber core 6 x 19 wire rope with an ultimate load of 13,400 lbs and a safety factor of 4:1 is 3,350 lbs. The correct answer is:
O 3,350 lbs
