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 B (Granular structure): Both steel (an alloy of iron with carbon, often with a granular/ crystalline structure) and aluminum (metallic, can have a granular structure) can have a granular structure.
• Option C (Relaxed when not damaged or formed): Both, when not under stress or damaged, are in a relaxed state.
• Option D (Work hardening): Both steel and aluminum exhibit work hardening (their strength increases with plastic deformation).
• Option A (Tensile strength): Steel generally has much higher tensile strength than aluminum. So tensile strength is not a shared property in the same way (or to the same extent) as the others.

Answer:

A) Tensile strength.
