Question

Quizplus · Accepted Answer

Heavy-duty coil springs have a larger wire diameter and thicker coils as compared to regular-duty coil springs. This makes them stronger and capable of carrying more weight. As a result, heavy-duty coil springs have a higher free height as compared to regular-duty coil springs to compensate for the added load they carry. Therefore, technician B is correct in stating that a heavy-duty coil spring has a shorter free height compared to a regular-duty coil spring. Technician A is incorrect in stating that heavy-duty and regular coil springs have the same wire diameter.
