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 9in. Wide, 8in. Deep, and 7ft long holds up 26542lb. What load would a beam 6in. Wide, 4in. Deep, and 19ft. Long, of the same material, support? Round your answer to the nearest integer if necessary.
