One mole of magnesium (6 × 1023 atoms) has a mass of 24 grams, and its density is 1.74 grams per cubic centimeter, so the center-to-center distance between atoms is 2.84 × 10-10 m. You have a long thin bar of magnesium, 2.8 m long, with a square cross section, 0.09 cm on a side. You hang the rod vertically and attach a 102 kg mass to the bottom, and you observe that the bar becomes 8.64 cm longer. From these measurements, it is possible to determine the stiffness of one interatomic bond in magnesium. 1) What is the spring stiffness of the entire wire, considered as a single macroscopic (large scale), very stiff spring?
