How is the direction of rotation typically specified in combination locks?

  1. By the position of the key

  2. As clockwise (CW) or counterclockwise (CCW)

  3. In degrees of rotation

  4. By the number of turns required

The correct answer is: As clockwise (CW) or counterclockwise (CCW)

In combination locks, the direction of rotation is typically specified as clockwise (CW) or counterclockwise (CCW). This terminology is essential for accurately dialing the combination to open the lock because many locks require a specific sequence of movements, including predetermined directions for turning the dial. For instance, a common instruction might involve starting by turning the dial clockwise to a certain number, then back counterclockwise to another, and so on. Understanding and following these directional cues is critical for successfully unlocking combination locks, as incorrect direction can lead to failure in opening the lock, even if the numbers are dialed correctly. The other options, such as key positions, degrees of rotation, or number of turns, do not directly convey the necessary directional movements required in the operation of combination locks.
