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" see-saw 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 see-saw????

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!
