Pneumatics Study Guide- Final Exam Questions and Answers Rated A+ What safety measures should be taken when working with pneumatic systems? Safety measures include wearing protective gear, ensuring proper ventilation, and regularly inspecting components for leaks or wear. What is the difference between single-acting and double-acting cylinders? Single-acting cylinders use air pressure to move in one direction, while double-acting cylinders can move in both directions by using air pres...
