While surfing I stumbled on a children's quiz show -- ~~Smartest Kid in
America -- just as they were asking a pulley question -- it went by too
fast to sink in but I think that a 120lb weight is held by a pulley which
is supported by cable with two legs through the pulley.
What is the tension in the cables???
The answer given was 40lbs.
Did I see correctly???
Did I hear correctly???
