**Reiny**, Tuesday, February 19, 2013 at 7:09pmmass x distance on one side = mass x distance on the other side

let the distance be x m from the heavier mass

35x = 18(1-x)

35x = 18 - 18x

53x = 18

x = 18/53 = .3396

the fulcrum should be appr 34 cm from the heavier load.

check:

34(35) = 1190

66(18) = 1188 , close enough for 2 digit accuracy.
