Picture the original as a 3d image and it's already balanced.

SpikedVerga - I tried to draw this out and can't figure out how making it 3d gives you anything other than a 3d unbalanced scale. What am I missing?

This can be done in 4 moves...

well i disagree with your photo because if it were to be like that the only way that that diagram would really be true is if the two weights were sat on a flat surface cause the middle suporting beam to sag. what im trying to say is that your diagram doesnt show the two weight s being the same weight

The solution posted by rookie1ja is absolutely correct. Only 5 sticks were moved, NOT 6. The bottom stick of the upper (right hand) triangle remains in place and becomes the right half of the balance beam, The two sticks making the rest of the right hand triangle, plus the stick making the original right half of the balance beam move down to make the new right hand triangle, the stick making the left hand of the balance beam moves down to align with the right hand portion, the stick representing the pivot/support is moved down to line up with the new position of the balance beam. Sketch it out and you'll see that only 5 sticks have been moved.

I have to agree with this comment....but it's also easily done by moving the upper 2 pieces of the right triangle, to point downward, then move the 3 'balancing' upper pieces of the puzzle slightly lower to bring the balance-bar to a level position and the far upper one slightly down along with the other two you just moved. Theorheticaly, it would be balanced.

the first one is right. the right triangle was not moved down, it was inverted. If you move down the "hook to the top match" on the left, it is parallel to the bottom of the triangle on the right.

please remember the described obtuse triangle required to solve this problem can not exist with the isosceles triangle describing the scales on the left..you have an imagined straight line that does not exist..this can not be solved..
