a little brain teaser..
hi ...i'm having a hard time figuring out this one. see attachment pic. a water coluumn, square based tube ( 1 x 1 meters ) - height 10 meters. what will be the amount for the red weight at one side of the see-saw in order to push a styrofoam cube sized( 1x1x1meters=1 cubic meter) . the force must be sufficient to push the styrofoam inside the water column 1 meter up (so it will be at 9 meters depth).
theoretically there is no friction, and there is a seal blocking the water from flowing down and out of the pipe.
ideas?
thanks
