(See the original thread on alt.machines.cnc, where Elson dissed me and I
thusly started the usual web-bristling, w/ the usual huff, puff, and
attendant dance. But really, he shouldna dissed me, man, shouldna dissed
But moving onwerd and forwerd:
Even tho I had it on good authority that no goddamm builder on earth uses
curvature ceptin builders of long-assed bridges, the image of oh-so slowly
of the earth did bring this to mind:
For a tall building building to be "truly plumb", *each wall*
would have to
be plumb, ie, lie exactly along the *line of the earth's radius*
, from the
point where sed wall touches the ground.
, then, the walls of a tall building must **
, just as
the earth's radii diverge, from the earth's center to the base of the
Rough calcs indicate that a 1500 ft tall building, w/ a 400' x 400' base,
would have its top floor about 1/2" longer on an edge than the ground floor.
Iow, a "properly" constructed building will be a very long truncated
pyramid, point-side down, base up.
If a skyscraper is constructed w/ strictly parallel walls, as far as gravity
is concerned there is actually a tipping "moment", sorta like the Leaning
Tower of Pizza.
Not significant, of course, but hey, 1/2" is 1/2".
Which gives the top floor an area of 160,400 sq ft, vs the ground floor's
160,000 sq ft.
Which is, hey, but another lawyer's/stockbroker's office, which is, hey, but
even mo' rent.
A tall building might have to be built pyramidally, *narrow end up*
the slight tipping moment of one (or both) of the walls not
lying strictly in line w/ the earth's radii.
Uh oh, there goes the lawyer's office....
I can see Elson now, w/ his gadget at the Sears tower....
