When selecting a terminal for an electric cable, which statement is true about strength requirements?

The correct answer emphasizes that the terminal's strength should be equal to that of the cable it is connecting. This is crucial in aircraft electrical systems to ensure that both the cable and terminal can withstand the mechanical stresses they may encounter during operation without failing. By matching the strength of the terminal to that of the cable, it helps to maintain the integrity of the connection under a variety of conditions, including vibrations, thermal expansion, and other forces that can occur in flight.

This requirement for strength balance significantly contributes to the overall reliability and safety of the electrical system, as a weaker terminal could lead to failure, resulting in potential operational issues or hazards. Ensuring that electrical connections are robust against such stresses protects the integrity of the electrical circuits throughout the aircraft.
