Fulcrum problem
Posted:
Oct 22, 2004 9:52 AM


Hi everyone,
I have a problem with teaching the students how to solve a particular problem.
It goes like this:
Where would you place the "fulcrum" of a "12 foot" seesaw if on one end sat a 868 pound gorilla and on the opposite end sat 124 pound woman? Again the board is 12 feet long and where would the fulcrum be place "under" the seesaw????
I have not the slightest clue about fulcrums and how they work. all I know is that if someone is double the weight of the person on the opposite end, the fulcrum should be twice as close to the heavier of the two? Am I right?
Any help with an answer and explaination to this problem would be much appreciated! Thanks!
