In the categorization of automation topics, which category name encompasses Pneumatics/Hydraulics for Working Elements?

• A. Factory Automation and Food Manufacturing
• B. Pneumatics/Hydraulics of Working Elements
• C. Electric Electronics of Working Elements
• D. Programmable Logic Controllers

Answer: (B)

Pneumatic and hydraulic actuation powers are the methods that convert fluid power into motion to perform work. In automation, Working Elements are the actuators—cylinders, rams, and hydraulic motors—that actually move parts and apply force. The category that best groups these power methods for the moving parts is Pneumatics/Hydraulics of Working Elements. This label directly references the two main actuation approaches used to drive movement, distinguishing them from categories that focus on control electronics or broad factory domains. Pneumatics uses compressed air, while hydraulics uses pressurized fluid, both serving as the physical means to make working elements operate.
