6. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE What is Pressure? PumpTank Hose Air Molecules Pressure is the same everywhere

7. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE What is Mechanical Advantage? Image Source: en.wikipedia.org/wiki/Lever

8. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE What is Mechanical Advantage? e.g. Hydraulic Lift 100 lbs 1900 lbs Piston Area = 20 in 2 Piston Area = 1 in 2 Pressure = ? Use 60ml and 10ml syringe to demonstrate mechanical advantage.

9. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE Pneumatic Cylinder Pressure P Area Force F Diameter Cross Section of PistonSide View of Cylinder How much force is exerted by the piston? If pressure = 60 psi and diameter = 1 inch: Area = pi x (1 in) 2 / 4 = 0.785 in 2 Force = (60 psi) x (0.785 in 2 ) = 47 lbs.

18. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE Lifter Kit – Reflection What was the hardest part to build? What was the most difficult part to coordinate? Why did we ask you to build this lifter as part of the challenge? How can you make the process more efficient?

19. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE The Challenge

20. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE The Challenge Objective To design a robot, to be built on challenge day in 2.5 hours, using only the supplied tools and materials, that can score as many points as possible. Deliverable Two portfolios on Challenge day Notes We are using the “with hands” variation.

24. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE Discussion Why is one shelf worth more points than the other? What if you design a robot that only works when using your hands? How long will you have to move cylinders? What tools/materials can you use in your robot on Challenge day? What are the contents of the Challenge kit you’ll get on Challenge day?

25. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE How to Maximize your Points!

26. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE Awards are given for each sub- category and for overall. Discussion How many points are determined without competing with your robot? What pre-challenge action can you take to get the most Teamwork Skills points? Or the most Interview Question points?

27. Fluid Power Workshop Day INSERT DATE HERE Fluid Power Challenge Day INSERT DATE HERE Know the Grader Rubric Show that device is structurally sound. 1-5 points. Team 1 -> Team 2 -> Which team is more likely to get points?
