How does tension affect a clover hitch knot?

The correct answer is that tension strengthens the knot. When a clover hitch knot is tied, it consists of overlapping loops that encircle an object, such as a pole or a beam. As tension is applied to the knot, the loops are drawn tighter together, which increases the friction between the surfaces of the rope and the object. This increased friction helps to keep the knot secure, preventing it from slipping or coming undone.

Understanding this property of the clover hitch knot is crucial for stagecraft and rigging applications where secure tie-downs are necessary to ensure safety and stability of equipment. The effectiveness of a clover hitch under load illustrates the importance of knot choice in various applications.
