Greetings all. My 14 year old son is doing an 8th grade science fair project on the impact of various knots on the breaking strength of a rope. He is a Boy Scout and enjoys hanging in his Blackbird by dynaglide whoopies. See him pictured on a recent trip here. Going to progressively lighter and thinner whoopies is what caught his interest in addition to doing some rock climbing this past summer.
He has a nice project outlined and is in search of a reasonable mechanism to actually measure the breaking strength of different types of rope when various different knots are tied in them. Of course a solution needs to be relatively affordable to build or buy and needs to be able to be accomplished by 14 year old.
Thoughts, ideas and pointers greatly appreciated.
