The safe load, L, of a wooden beam supported at both ends varies jointly as the width, w, and the square of the depth, d, and inversely as the length, l. A wooden beam 8in. wide, 7in. deep, and 2ft long holds up 27412lb. What load would a beam 5in. wide, 6in. deep, and 18ft. long, of the same material, support? Round your answer to the nearest integer if necessary.
