Re: Bridge lowering force calculation

The forumula doesn't add any margin, but depending on some assumptions it could be a high starting value. One of our early designs was pushing about 10" up the ramp with about 28 pounds vertical, and that was "just" enough.

The calculations say it takes about 28 - 29 at that point.

From some of the posts in other threads, it seemed that some teams were not sure at all what it took to lower the bridge - I was giving some guideance.
