The maximum safe load L of a horizontal rectangular beam varies jointly with the width of a beam and the square of the thickness and inversely with its length. If a 4 x 4 inch beam that is 8 feet long will support a load of 1000 pounds, how much will an 8 x 8 inch beam that is 16 feet long support?
