When slings are used at an angle from vertical, what happens to the load on each sling?

Explanation:
When slings are used at an angle from vertical, the load on each sling increases. The weight being lifted is supported by the vertical components of both sling tensions. If theta is the angle each sling makes with the vertical, the tensions must satisfy 2 T cos theta = W, so T = W / (2 cos theta). As theta grows (the slings move farther from vertical), cos theta decreases, causing T to increase. So, the more the slings tilt away from vertical, the higher the load each one must carry.
