Young's modulus for aluminum is 6.2 × 1010 N/m². The density of aluminum is 2.7 grams/cm3, and the mass of one mole (6 x 1023 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 x 1010 N/m², the density of lead is 11.4 grams/cm3, and the mass of one mole is 207 grams. Make a note of these results, which we will use for various purposes later on. Note that aluminum is a rather stiff material, whereas lead is quite soft.

Question
**Educational Content on Material Properties:** **Young's Modulus and Spring Constant Calculation** Young's modulus for aluminum is \(6.2 \times 10^{10} \, \text{N/m}^2\). The density of aluminum is \(2.7 \, \text{grams/cm}^3\), and the mass of one mole (approximately \(6 \times 10^{23}\) atoms) is 27 grams. If we model the interactions of neighboring aluminum atoms as though they were connected by springs, we can determine the approximate spring constant of such a spring. **Analysis Using Lead:** The same analysis can be repeated for lead: Young's modulus for lead is \(1.6 \times 10^{10} \, \text{N/m}^2\), the density of lead is \(11.4 \, \text{grams/cm}^3\), and the mass of one mole is 207 grams. Make a note of these results, which will be useful for various purposes later on. Note that aluminum is a rather stiff material, whereas lead is quite soft. **Part 1: Aluminum** Your task is to calculate the spring constant for aluminum: - \(k_{s, \text{aluminum}} = \underline{\hspace{3cm}} \, \text{N/m}\) Your last answer was incorrect. You have used 3 out of 4 attempts. You can save your progress to work on this problem again later. Saved work will be automatically submitted on the due date, and auto-submission may take up to 10 minutes. **Part 2: Lead** Next, calculate the spring constant for lead: - \(k_{s, \text{lead}} = \underline{\hspace{3cm}} \, \text{N/m}\) You have not yet used any attempts for this question. Save your work and consult eTextbook and Media as needed. **Graphical and Diagram Explanation:** The page primarily focuses on textual content and input fields for calculations. The student's responses are submitted through these fields, and feedback is provided based on attempt counts.
