1: An aluminum alloy (E = 70 GPa) bar of circular cross section consists of uniform and pered sections as shown. The diameter of the tapered section varies linearly from (50 mm) at e top to (20 mm) at the bottom. The uniform section at the top is hollow and has a wall ickness of (10 mm). Determine the load P that will cause a total elongation of (3.07 mm). eglect the weight of the bar.

QI: An aluminum alloy (E 70 GPa) bar of circular cross section consists of uniform and
tapered sections as shown. The diameter of the tapered section varies linearly from (50 mm) at
the top to (20 mm) at the bottom. The uniform section at the top is hollow and has a wall
thickness of (10 mm). Determine the load P that will cause a total elongation of (3.07 mm).
Neglect the weight of the bar.
