A mechanical device inserted into the energy path of an air-operated clamping device to physically prevent movement is known as what?

• A. damping
• B. easing
• C. regulating
• D. blocking

Answer: (D)

Blocking means placing a physical barrier in the energy path so the actuator cannot move. In an air-operated clamp, a blocking device stops the cylinder’s motion by intercepting the air flow or the piston path, effectively locking the clamped part in place regardless of pressure.

Damping slows movement by absorbing energy, but it doesn’t completely halt it. Regulating controls parameters like pressure or flow to govern speed or force, rather than preventing motion altogether. Easing refers to smoothing or easing the start/stop, not blocking the motion. So the term that describes physically preventing movement is blocking.
