The statement that the D/d ratio strongly affects performance is indeed accurate when discussing synthetic web slings. The D/d ratio refers to the relationship between the diameter of the load-bearing surface (D) and the diameter of the sling (d). A larger D/d ratio indicates that the sling is wrapped around a larger surface, which reduces the stress on the sling and allows for better load distribution. This is crucial for synthetic web slings as it helps to prevent damage from edge-loading or sharp surfaces during lifting operations.

The relevance of the D/d ratio for synthetic web slings stems from the materials and flexibility of the slings. Unlike wire rope, which has a more rigid structure, synthetic web slings can conform better to different shapes, making the D/d ratio particularly impactful in terms of safety and performance. Thus, when using synthetic web slings, ensuring an appropriate D/d ratio is vital for maximizing their strength and longevity during lifting tasks.
