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.)

P.1.9. A bar of mild steel has a diameter of 75 mm and is placed inside a hollow aluminum cylinder of internal diameter 75 mm and external diameter 100 mm; both bar and cylinder are the same length. The resulting composite bar is subjected to an axial compressive load of 1000 KN. If the bar and cylinder contract by the same amount, calculate the stress in each. The temperature of the compressed composite bar is then reduced by 150°C but...
