Question

post-test
when performing steel and aluminum repairs, consider all the following except:
a. if the steel is embedded in aluminum, it can cause galvanic corrosion.
b. steel lacks memory and is much harder to work with than aluminum.
c. aluminum lacks memory and requires special repair tools.
d. steel has memory and is much easier to work with than aluminum.

Explanation:

To solve this, we analyze each option:

• Option A: Steel embedded in aluminum can cause galvanic corrosion (correct consideration for repairs).
• Option B: Steel lacks memory (shape - memory property) and is harder to work with than aluminum (correct consideration).
• Option C: Aluminum lacks memory and needs special repair tools (correct consideration for repairs).
• Option D: Steel does not have memory (unlike some materials like shape - memory alloys) and is not easier to work with than aluminum. This statement is incorrect and thus the one we do not consider when performing steel and aluminum repairs.

Answer:

D. Steel has memory and is much easier to work with than aluminum.
