PLEASE HELP! I DO NOT KNOW WHAT TO DO? The maximum weight that a rectangular beam can support varies jointly as it's width and the square of its height and inversely as its length. If a beam 1/2 foot wide, 1/3 foot high, and 10 feet long can support 12 tons find how much a similiar beam can support if the beam is 2/3 foot wide, 1/2 foot high, and 16 feet long.
