A: The right call isolates the life-limiting damage in the stated environment so the RPN action hits material and geometry. High-cycle fatigue matters, but without a corrosive driver it doesn't explain salt exposure; galvanic effects need a nobler mating metal and continuous electrolyte; oxidation at these temperatures on 6061-T6 stays superficial.

A: The target answer matches elastic bending theory so you can judge whether the FEA stress is sane. Halving the stress by smearing the load ignores the cantilever moment; jumping to plastic section modulus mixes limit analysis into an elastic check; dividing by an arbitrary safety factor corrupts the comparison.

A: This path confirms geometry reality against controlled datums before chasing digital ghosts. Rebuilding CAD doesn't tell you what's built; torque marks address process, not fit; material certs won't move holes.

A: The correct pairing maximizes potential difference and keeps the aluminum anodic in an electrolyte. Zinc plating sacrifices itself and helps; bare carbon steel sits closer in the series; anodized aluminum largely breaks the circuit.
