Unit 3.2: Under Pressure

Objectives

• In Unit 3.2 Fluid Power, students learn the fundamentals of hydraulic and pneumatic fluid power. In the first activity, students explore the differences between hydraulic and pneumatic systems. Students are introduced to mathematical formulas and concepts that support fluid power engineering. In the next activity, students complete a problem set designed to challenge their knowledge of fluid power mathematics. At the end of the lesson, students are tasked with designing and building a working hydraulic system.

Classroom Activities

1. Prayer.
2. Disassemble your projects and put the parts neatly away. Asked the TA for help if you don't know where it goes.
3. Complete Activity 3.2.1 Pneumatics
   • Use the slides Introduction to Pneumatic Power
   • Around slide 23 is a slide with the components of a pneumatic system. You need to look at the slide notes also on that page.
4. Complete Activity 3.2.2 Fluid Problems
5. See myPLTW 3.2.2. There are links at the very top to hydraulics and pneumatics explaining the formulas. The slides also will help.
