Math Problem Statement
The maximum weight that a rectangular beam can support varies jointly as its width and the square of its height and inversely as its length. If a beam
one third13
foot wide,
one half12
foot high, and
1919
feet long can support
1010
tons, find how much a similar beam can support if the beam is
one third13
foot wide,
one third13
foot high, and
1111
feet long.
