Is the gate question a trick? H has the brace the wrong way round.

Bill
tesnd to work either way.

No the force has to be compression on the brace.

It does not *have* to be. Granted that is the traditional way, but it
will also work in tension if its well fixed. What is required to prevent
racking of the gate is a triangulated cross member. Having it in
compression works well since it can be notched into the other timbers
and will hence work and stay put even without much in the way of
fixings. In tension it relies more heavily on the fixings, but will
still work.

As has been said though, in the context of the question, where all the
other alternatives simply had variations on right angle joints and no
brace, its the only clear correct answer.
