How do sling angles affect the stress on each leg of the sling?

• A. Lowering the angle will not change the stress
• B. Lowering the angle will double the stress
• C. Lowering the angle will overload the sling
• D. Lowering the angle will increase the stress on each leg

Answer: (D)

Sling angles significantly influence the distribution of stress on the legs of a sling. When the angle of the sling is lowered, it causes an increase in the effective load carried by each leg of the sling. This is due to the geometry of the situation: as the angle decreases, the vertical component of the load remains the same, but the horizontal component increases. This leads to a higher tension in the sling legs. As the angle gets closer to horizontal, the tension in each leg rises because the weight is being distributed over a longer distance. In essence, lower angles result in more force being concentrated on each leg, thereby increasing the overall stress. This principle is crucial for safe lifting practices, as exceeding the rated capacity of the sling can lead to failure and accidents. Understanding this relationship emphasizes the importance of maintaining appropriate sling angles during lifting operations, ensuring that the load is managed safely and effectively.
