3. Like dogs shouting at the moon,
Or armor worn by trees,
Like a sharply spoken command,
Or a tiny vessel upon the seas.

That problem had been bugging me batty. :)

Maths Question: Pipes stacked in trucks.

I was thinking recently about the way truck deliver large pipes.

You can see in this image that the pipes are packed like this:


Per unit volume, however, this packing is more efficient:

(and sometimes trucks do use this packing)

If you were to bind the second 'hexagonal packed' cylinders in a square container, there would be wasted space in every second row, meaning that for small numbers of pipes, the 'square packed' method can pack tighter. (Assuming the container has sides of a whole number multiple of diameter 2r.)

What I'm wondering, is at what length n will the hexagonal packed method break even and become the optimum stacking method? Where n is the whole number length of sides of the bounding square, in diameters.

I recognise that this is a surface area vs perimeter problem, but I can't work out the equation.



All the results I found googling this seemed to have the problem in reverse, i.e. for given number of circles, what is the arrangement which can be bound in the smallest square of arbitrary size, or talk about how close spheres can pack, without talking about the break even volume, so I can't extrapolate from there.

This has baffled me, so I'd very much appreciate a hand in working this out. :)

Regards, Scarab.

What be the name of the group for pirates over 65 who's seafaring days are behind them?

I think I know what you're getting at, but I have no idea how the answer would be phrased.

Are you just looking for the acronym?

Glad you took the gamble but no it's not gods.

I was thinking that it was a little ostentatious a claim for a riddle to make. :P

1. (4 letter word)
You can count on them, though
Some would rather curse them.
You can speak dear to them,
Though we all know 'tis just in vain.

You guys rock, these podcasts are the perfect inspiration for game making. For that i thank yee!

Agreed. Never fails to make me dust off the old game ideas notebook on my desk.  :-D

Ah, I was thinking 'snail' for that last one, but I didn't think snails were bloodless.
