A steel wire of length 1.6 m and diameter 0.80 mm is joined to
an aluminum wire of identical dimensions to make a composite wire
of length 3.2 m. Find the resulting change in length of this
composite wire if an object with a mass of 5.00 kg is hung
vertically from one of its ends. (Neglect any effect the masses of
two wires have on the changes in their lengths.)
