That has crossed my mind also Dave. With the little thought that I have put into it, I just figured that yes, in theory, you are correct, but in practice it doesn't seem to matter much. I guess you could always look at the ratio of the rib spacing at both ends of the ribs and add and subtract a similar ratio to/from the rib width. But I suspect it just doesn't make a significant difference. But then again, even though the ribs are spaced closer together on one side of the bridge than the other, the total load support is the same on both sides of the bridge - which, I would thing, you would want. Perhaps because the ribs act as a spring, you would really want to keep the ribs even dimensioned, regardless of their spacing. Don't really know. Terry Farrell ----- Original Message ----- Something I've wondered about on the radial rib patterns is that the ribs end up much closer together on the bent side than on the cut-off bar side. Is that a concern in terms of uniform stiffness from one side to the next and should that be compensated for somehow by, say, stopping every other rib short of the rim by some amount on the bent side, and, if so, does it create a problem of any type terminating a rib short of the rim? Or, I suppose, you could taper every other rib to a greater degree on the bent side achieving it's full reduction in height farther away from the rim.
