In this fulcrum, the weights are perfectly balanced. How far must the fulcrum be located from the 40 lb. weight if the bar is 11 feet long? x (to the nearest tenth) =
Accepted Solution
A:
the complete question in the attached figure
we know that if the weights are perfectly balanced 40*(x)=50*(11-x) 40x=550-50x------------> 50x+40x=550--------------> x=6.11
