Final answer:
The safe working load of a wire rope is the maximum load it can safely handle, which is typically a fraction of its breaking strength to provide a safety margin.
Step-by-step explanation:
The safe working load of a wire rope is the maximum load it can handle without risking failure. It is an essential concept in engineering and construction because it ensures the safety and reliability of lifting and rigging equipment. The safe working load is not the breaking strength of the rope but a fraction of it to provide a safety margin. This value is often specified by the manufacturer or determined by industry standards. In some cases, it may be approximately equal to one-third or one-fifth the breaking strength of the rope, depending on the type of rope and its application.
