I need to make a rope from 2 single sized bedsheets and a pillowcase. The rope must be strong enough for a 225 lb person to safely decend from a 4 story window to the ground. How many pieces should each bedsheet be torn into in order to make a rope strong enough to hold the person that is decending the rope? I have no room for trial and error. This has to be correct on my first attempt or else the rope will break because it's not strong enough; or the rope will be too short to reach the ground. The rope will only be used once, unless I can figure out a way to get the rope untied from the 4th story window when I'm on the ground.
