| Abstract: | In this paper, through indoor and outdoor experiments,the commonly used double and triple turns Prusik knots are measured with 10.5 mm and 12.5 mm main ropes.The force,deformation, and failure strength of Prusik knot are tested in different condition. According to the structural characteristics of Prusik knot and various force test results,the paper discusses the safety and stability of Prusik knot. Through introduction and research, it can provide a reference for the safe application of Prusik knot in the fire fighting and rescue work and give inspiration to the experimental research of other knots. |
