When using any lifting slings, which of the following factors does NOT affect capacity?

The correct answer is based on understanding the relationship between the various factors that influence the capacity of lifting slings. When assessing lifting slings, the weight of the load, choke factors, and angle factors directly impact the sling's capacity.

The weight of the load is crucial because the capacity of the sling must be sufficient to safely lift the intended weight. Additionally, choke factors pertain to the way the sling is rigged and the configuration used, which can either increase or decrease the effective capacity based on how the load is applied to the sling. Angle factors consider the angle at which the sling is used; this can create different load distributions across the sling, affecting its ability to lift safely.

In contrast, the length of the sling does not inherently affect its lifting capacity. While sling length can influence how a load is positioned and the ease of handling, the fundamental capacity of the sling remains determined by its material strength and the configuration in which it is used rather than purely its length. Therefore, the length does not directly change the maximum load a sling can handle, making it the factor that does not affect capacity in the context of this question.
