The maths is really quite fun (this from the Wiki link)
http://www.algobeautytreb.com/trebmath35.pdf
as is the maths of the Roman cross-bow type catapult, which is
also very dependent on the properties of the sinew which they
used for the springy bits.

That's just plain anal ...
Oh I don't know. Have you ever been to Bluewater?

Some kind of shopping emporium, isn't it ?

No
A trebuchet could be useful there.

I could make this a commercial venture! The original 'Warwolf' could
chuck a 100kg ball 200m. It was 20m high, so transport might be a
problem, but how much a day could you charge for destroying places like
Bluewater?


And where would "they" go without Bluewater? Got to think of the
consequences on other places.

There is that, I suppose.
