One mole of titanium (6 1023 atoms) has a mass of 48 grams, and its density is 4.54 grams per cubic centimeter, so the center-to-center distance between atoms is 2.60 10-10 m. You have a long thin bar of titanium, 3.0 m long, with a square cross section, 0.15 cm on a side. You hang the rod vertically and attach a 142 kg mass to the bottom, and you observe that the bar becomes 1.55 cm longer. From these measurements,...
