a 21.00 m steel beam with 6.00 cm x 6.000 cm cross-section is supported at opposite ends by two wires of equal length but of different composition in diameter. One wire composed of copper has a diameter of .8500 mm The other wire is made of aluminum. If the steel beam remains perfectly level find the diameter of the aluminum wire
