In a symmetric 3-leg bridle sling, what happens to capacity as angle θ increases?

Explanation:
Sling capacity depends on how the load is shared among the legs as the angle changes. In a symmetric 3-leg bridle, each leg carries a tension that has to provide the weight vertically. If each leg makes an angle θ with the vertical, the vertical components of the three leg tensions sum to the load, so the maximum load you can lift before any leg is overstressed is Wmax = 3 × (per-leg capacity) × cos θ. As θ increases, cos θ decreases, so Wmax decreases. This means the overall capacity falls with larger angles because the legs must carry more tension to produce the same vertical lift, reducing how much weight the system can safely handle.
