The diameter of an object used as an anchor with a tensionless hitch should be how many times the diameter of the rope?

When using a tensionless hitch, the diameter of the object being used as an anchor is crucial for effective functioning and safety. The requirement for the anchor's diameter to be more than four times the diameter of the rope ensures that the tensionless hitch can effectively grip the anchor without slipping or damaging the rope.

A larger anchor diameter allows the hitch to maintain a secure connection by distributing the load over a wider area. This distribution reduces the risk of the rope cutting into the anchor, which can occur when the diameter is insufficient. An anchor that is more than four times the rope's diameter minimizes the potential for failure and enhances the overall safety and performance of the rescue setup.

This principle focuses on the physics of friction and surface area, which are vital in ensuring that the hitch remains secure under load. Therefore, ensuring the anchor has a diameter proportional to that of the rope is essential for safe and effective rescue operations.
