What is Mechanical Advantage? e.g. Hydraulic Lift 100 lbs

1900 lbs

Piston Area = 20 in2Piston Area = 1 in2

Pressure = ?

Use 60ml and 10ml syringe to demonstrate mechanical advantage.

Pneumatic CylinderPressure 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 in2

Force = (60 psi) x (0.785 in2) = 47 lbs.

Diameter*3.14Area

Pressure * Area Force

Divide Tasks

Elect Group Leader

Assign Roles:

1) Leader (Check progress of parts and help where needed)

2) Wood Cutter / Later Arm Builder3) Cube Maker 14) Cube Maker 2

Without dividing tasks and working in parallel, you won’t complete the activity. (Same on challenge day)

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?

The Challenge

ObjectiveTo 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.

DeliverableTwo portfolios on Challenge day

NotesWe are using the “with hands” variation.

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?

Awards are given for each sub-category and for overall.

DiscussionHow 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?
