The UIAA standard power rope design standard is that a 80KG climber falls off when the falling coefficient is 2, and its impact force does not exceed 12KN Of the force limit, the experimental surface of the human body in a short time to withstand the impact of 12KN), and to achieve this purpose is to rely on the elasticity of the main rope to complete, like bungee cord power cord to absorb the sudden momentum. All the other equipment is designed around this premise. The long rope can stretch longer and absorb more energy, which is why the impact force of the same 4-meter drop and 20-meter drop is as large as the falling coefficient of 2, which is about 9 KN)
