Climbing ropes calc

Every climber has heard the folklore: "factor two is deadly," "the top piece feels one and a half times the fall," "a rope is dead after one big whip." Climbing ropes calc replaces the folklore with arithmetic you can check. Climbing ropes calc fits a force–strain curve to the two numbers printed on every dynamic rope — rated impact force and rated elongation — then solves the energy balance for any fall you can describe. Set the climber's mass, how far above the last piece you are, the slack in the system, and how much rope is out. The workbench answers with peak force on the rope, elongation, stretch in metres, energy absorbed in joules, the load on the top piece, and what it all means for the rope's remaining life. The Seek tab inverts the same equations. Pick a force ceiling and Climbing ropes calc tells you the tallest fall that stays under it, the fall factor it corresponds to,…
