• A. Gears
• B. Sensors
• C. Cylinders
• D. Motors

Answer: (C)

The idea being tested is how actuation and flow control work together to move parts in an automated feed path. A single solenoid directional control valve directs compressed air to pneumatic cylinders, which provide straightforward, repeatable linear motion. For feeding screws, this linear motion is essential to push each screw into the next station reliably and at the right speed and position. Having three cylinders allows coordinated actions in the feed cycle—pushing a screw into place, gripping or stabilizing it, and then resetting for the next cycle—so the process stays smooth and fast. Gears would introduce rotational motion, motors would require a different drive setup for rotary or precise positioning, and sensors alone don’t produce motion; they only detect or measure. That’s why cylinders are the appropriate actuators in this configuration.
