If a synthetic rope has a breaking strength of 7,600 lbs, what is the maximum gross load that can be lifted?

The maximum gross load that can be lifted by a synthetic rope is determined by its breaking strength, which in this case is 7,600 lbs. The breaking strength represents the maximum force the rope can handle before failing. To ensure safety and account for dynamic loads, conditions such as the lifting method, angle, and environmental factors should be considered.

It is essential to maintain a safety factor in lifting operations. A common practice is to use a safety factor of at least 5:1, meaning that the working load limit (WLL) is typically a fifth of the breaking strength. Therefore, if the breaking strength is 7,600 lbs, the safe working load would be around 1,520 lbs (7,600 lbs ÷ 5).

Therefore, the maximum gross load that can be lifted safely is not just the breaking strength but a fraction of it, ensuring safety during the lifting process. In this context, the choices do not reflect a safe working load based on the breaking strength of the rope. A better understanding of the principles of lifting, the usage of safety factors, and the potential for dynamic loads would better guide the answer towards a safe operational load.
