The theme of today is building a scissor lift model, which is the application of the pneumatic system of the last lecture. In this section, the built scissor model consist pneumatic components from cylinders and pumps to the air valve, the air tank, and the manometer. With the built model, the students got a deeper understanding of the design philosophy and working principles of the pneumatic system, which built a solid ground for the next following more advanced pneumatic application models. This section is a good example explaining the air storage system in the pneumatic system.
The STEM information behind this section is the application of pneumatic systems. The cylinder piston rod force output can be calculated by multiplying the air pressure with the piston area. All the students finished the model and the experiments. The application sections interest them more than the principal model introductions.
