A knot does not change the strength of the rope. True or False?

• A. True
• B. False
• C. Sometimes
• D. Not enough data

Answer: (B)

Tying a knot changes how a rope carries load. When you knot a rope, you introduce bends, contact points, and friction that alter the load path. Those features create stress concentrations and micro-damage spots, so the rope does not bear as much load as it would in a straight, unknotted condition. Different knots and rope materials will reduce strength to varying degrees, but the general rule is that a knot weakens the rope rather than leaving its strength unchanged. So the statement is false: a knot does change the rope’s strength. In practice, when rigging, you evaluate whether a knot is necessary and, if so, choose knots that minimize strength loss and understand the corresponding safety factors.
