The concept being tested is how the safe working load is determined and what it represents. Safe working load is the maximum load that equipment is designed to handle safely under normal use, taking into account uncertainties like dynamic forces, wear, and potential defects.

The correct statement expresses that the safe working load is the breaking strength divided by the safety factor. This creates a conservative limit so that even under peak or dynamic loads, the equipment won’t reach failure. For example, if a lifting rope has a breaking strength of 20,000 N and the safety factor is 5, the safe working load would be 4,000 N. This margin protects against shock loading, wear, and material defects.

Why the other ideas don’t fit: the safe working load is not the load you are lifting at that moment, but a maximum safe limit you should not exceed. It’s not determined by the safety factor alone because you must also know the actual breaking strength of the equipment; both values are needed. And it isn’t the same as the breaking strength itself, since the safety factor reduces that strength to a practical, safer limit.
