Check that you're posting in the "ask a question" section, not the "responses" section. Also, only team accounts (FRC#) are able to ask questions; your team's username and password are displayed in TIMS.

If that doesn't work, e-mail frcteams@usfirst.org with the problem.

(with aluminum angles on each edge and corner reinforcement) to the frame with its top edge in the same plane as the top of the frame. The top edge (1") of the bumper would be "fully supported" but a major portion of the bumper
would not have frame behind it. Does this meet the intent of the rule?
I'm not sure I want to hear the answer to that question...unless it's "we're not going to comment on specific designs".

The Q&A has already set something of a precedent with the ruling on one particular design using 0.125 in aluminum, and as a consequence, people are wondering whether their perfectly-reasonable designs are valid.

This is a clause in the bumper rule that needs to be enforced as little as possible (within the rules, of course). Teams that build poor structure will have only themselves to blame, if something breaks—they've been warned; everyone else shouldn't be forced to worry unduly about the ramifications of this nebulously-defined specification. (Closer to the season, a consensus will probably emerge as to how this clause will be enforced; that doesn't really help now, though.)
