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 5in wide, 4in deep, and 2ft long holds up 34387lb. What load would a beam 8in. wide, 2in. deep, and 15ft long, of the same material, support? Round your answer to the nearest integer if necessary
