I agree, Duncan's work is fascinating. A tree man who actually seeks to
answer the questions we ponder, with science. I'm looking forward to his next
publication, to enable further pondering on my part.
This stuff by MIT is brilliant, not just mimicking the structure of tree
forks, but actually using them within the structure like the ship builders of
olden times. But now also with the design led by the morphology of the forks
too. Superb.

The work that Duncan has done is fascinating, but at the risk of sounding
dismissive (which I'm not), anyone who has split firewood in any quantity
with an axe will know that it is nigh on impossible to separate a fork.
When looking at forks one is looking to see any indications of inherent
weakness from whatever stimulus. One the basis that trees are
self-optimising there is no reason to suspect that a fork is week, and from
looking at storm damage (from even before 1987!) some forks failed, others
didn't and there was a stem/branch fracture above others.
On another tack, perhaps we could revert to the main function of uktc which
is to exchange knowledge and opinions, and to ask questions, while keeping
the blood pressure normal!

The "forks" depicted appear to be hardwoods.
