Young's modulus for aluminum is $6.2 \times 10^{10} \mathrm{~N} / \mathrm{m}^{2}$. The density of aluminum is 2.7 grams $/ \mathrm{cm}^{3}$, and the mass of one mole ( $6 \times 10^{23}$ atoms) is 27 grams. If we model the interactions of neighboring aluminum atoms as though they were connected by springs, determine the approximate spring constant of such a spring. Repeat this analysis for lead. Young's modulus for lead is $1.6 \times 10^{10} \mathrm{~N} / \mathrm{m}^{2}$, the density of lead is 11.4 grams $/ \mathrm{cm}^{3}$, and the mass of one mole is 207 grams. Make a note of these results, which we will use for various purposes later on.
