But in all seriousness, we've fallen into this trap and been called on it. No more useless teasers from us!

Also the reason why FIRST said that moving the batteries from 28" to 30" causes the ramp to move. There is a tolerance range on when the ramp will tip. It will be interesting to see what happens during the game when teams are almost balanced and then cross this threshold. Greg Sam,

Given the shift in moment of inertia and the torque, the two inches may/may not have an effect on tipping.

The trick is to balance the ramp side to side before increasing the mass. Make sure the ramp is completely built, with lexan and all before doing this. Greg Jeff,

Tried figuring out some math but it didn't work out in practice. We ran into this problem too. Tried figuring out some math but it didn’t work out in practice.
