Question

post-test
steel and aluminum share the following properties except:
a. tensile strength.
b. granular structure.
c. relaxed when not damaged or formed.
d. work hardening.

Explanation:

To solve this, we analyze each option:

• Option A: Steel generally has higher tensile strength than aluminum, so this is a property they don’t share (or share differently, making it the exception).
• Option B: Both steel (a metal alloy) and aluminum have a granular (crystalline) structure at the microscopic level.
• Option C: Both return to a relaxed state when not damaged or formed (elastic behavior in undamaged conditions).
• Option D: Both exhibit work hardening (strengthening from plastic deformation).

Answer:

A. Tensile strength.
