What is Mechanical Advantage? e. g. Hydraulic Lift 100 lbs 1900 lbs Piston Area = 20 in 2 Pressure = ? Fluid Power Workshop Day <Insert Date> Piston Area = 1 in 2 Fluid Power Challenge Day <Insert Date>

Pneumatic Cylinder Diameter Pressure P Area Force F Side View of Cylinder Cross Section of Piston 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/ in 2 Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>

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? Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>

The Challenge Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>

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. Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>

Discussion Why is one destination position 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?

How to Maximize your Points! Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>

Awards are given for each subcategory 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? Fluid Power Workshop Day <Insert Date> Fluid Power Challenge Day <Insert Date>
