What is a sign of a potential problem when inspecting an apparatus steering wheel?

The indication of turning more than 10 degrees without any movement of the tires is a significant warning sign during an inspection of the apparatus steering wheel. This condition may suggest that there is a malfunction within the steering mechanism, such as a disconnection between the steering wheel and the steering linkage, or problems with the power steering system.

In standard vehicle operation, a small amount of play in the steering wheel is normal; however, a turn exceeding this threshold without translating into tire movement can indicate serious mechanical issues. Such problems could impair the driver's ability to control the vehicle, thus posing a safety hazard, especially in emergency response situations where maneuverability is crucial.

Other options describe either not significantly concerning conditions (like turning smoothly, which is what you want to feel) or less precise thresholds that do not align with typical standards used to assess steering responsiveness.
