Hello, Bill. I am not sure if the laws of physics apply to fall arrest standards. I think it is more like the manufacturer's, and OSHA's , CYA policy. Regards, Lou

Well, sure: if a 200-pound worker falling five to six feet can generate 2,500 pounds of force on the rope when it reaches its limit, that's your basic physics right there.
