Re: Bridge question
Same problem.
I also noticed that our bridge is a bit flimsy. Lots of torsion when two people walk over it. I'll be adding some 2x4 blocks between the 3/4" trapezoidal supports, and from these I'll try hanging weights. I wish I had saved last year's dead batteries!
And Joe Johnson, thank you for the explanation. My first instinct (as a physics teacher) was to claim that it should not matter how massive the bridge was. After checking the actual game pieces, and seeing the hinge points were at the same positions, I was trying to figure out how increasing the mass will matter.
The fact that the hinge points are off-center does indeed mean that the CG will be lifted when the bridge tips up.
I'm only upset that I didn't see it myself
