Question

28 ccc cause and effect youngs modulus is a measure of a solid materials stiffness. a highly ductile material will typically have a very low modulus. the table shows several different metals, their crystalline structure, and their youngs modulus. describe the pattern you observe and explain the connection between structure and stiffness. youngs modulus

Explanation:

Compare Young’s modulus values for BCC (Chromium:279 GPa, Iron:210 GPa, Tungsten:411 GPa) and FCC (Copper:110 GPa, Silver:83 GPa, Aluminum:70 GPa, Lead:16 GPa) metals. All BCC metals have higher Young’s modulus than FCC metals. Young’s modulus measures stiffness, so BCC crystalline structure correlates with greater stiffness than FCC structure.

Answer:

Metals with BCC crystalline structure have higher Young’s modulus (greater stiffness) than those with FCC structure.
