The subject line of "fasteners" is quite apropos to a thought that came,
unbidden, into my head the other day.
When one is carrying a sheet of airtight material such as corrugated iron or
plastic, a length of timber or even a slab of hay, one is conscious of the
pressure imposed upon it by even a slight wind, so just imagine the tons of
pressure pushing against the wall of a house in a gale.
Now, that wall is held together by the * fasteners, which in most cases, is
just a quantity of nails and screws.
It is easy to snap one twig, but impossible to snap a bundle of twigs of a
similar diameter! Is the enormous pressure-resisting strength of a wall merely
a product of the combined strength of those fasteners?
