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.

A: This result respects how GD&T defines position as a cylindrical zone. Using full diametral clearance doubles what's allowed; splitting error across bolts isn't how worst-case stack works; process capability doesn't change geometric limits.

A: This step ensures the data maps to the released definition you're signing off. Calibration matters but doesn't fix wrong geometry; non-critical finishes don't gate fit or function; packaging comes later.

A: The correct concern targets the material that will actually lose section in this couple. Titanium is noble and resists pitting here; SCC isn't credible at these conditions; oxidation doesn't govern joint life.

A: This choice aligns DFMEA input with physics rather than numerical artifacts. Blindly taking the peak rewards a coarse mesh; averaging has no basis; dismissing the model throws away a valid screening tool.

A: This action accounts for real stack contributors before hardware exists. Looser mates hide problems; nonlinear contact is overkill for coating stack; surface finish doesn't add material.

A: This value directly reflects material margin without policy bias. Inverting the ratio flips the meaning; forcing a default masks real risk; applying an unstated knockdown double-counts degradation.
