i know this question was asked, but it only got one answer.

For those of you who have built a bridge, would you know how much force in lbs it takes to lift up or push down that bridge.....from either ends?

We've build our bridge and have put some weight on the ends to see how much weight is needed to move the bridge. We've come to believe that it takes ~5 pounds to move the ramp from its up position to its down position, and ~3 pounds on the upper end to ballance it.

I am on the TechnoKats and we have built a field to scale with goals and bridge, we have been busy building this years robot and look forward to the challenge of the game. We have figured it look 50 lbs. of force to move it with a robot (TKO) balanced in the middle, but with out a robot on it it took about 17 lbs. of force to raise or lower the bridge. Hope that will help you some.
