The safe load, l, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length. a wooden beam 2 inches wide, 7 inches high, and 192 inches long can hold a load of 2480 pounds.
what load would a beam 4 inches wide, 6 inches high, and 120 inches long, of the same material, support?
(round off your answer to the nearest integer.)
