The Challenge Design a zip ride trolley system with a braking mechanism that delivers a safe and smooth ride on a zip line.

The Criteria 1. The materials must be easily obtainable from home or school.

2. The system must transport a 1 kg mass along an approximately 3 m zip line at various elevations and stop at the end of the zip line.

3. The braking mechanism and trolley can be one unit or separate units.

4. The zip lines used will be the ones set up in the lab. They will be made of 1/8” flexible galvanized steel wire.

5. Once the trolley is released, no team interaction with the zip line trolley and/or braking mechanism can occur.

The Process In your teams: 1. Research existing zip line trolley systems for design characteristics and function. Some websites to consider:

a. http://adventure.howstuffworks.com/zip-line1.htm

b. http://en.wikipedia.org/wiki/Zip-line

1 c. http://www.ziplinerider.com

2. Brainstorm ideas for the type of zip line trolley system you want to design. Some ideas to consider:

a. What design characteristics will contribute to the smoothness of the ride?

b. How will you brake the zip line trolley at the end of the line?

c. How will you determine the safety of your design?

d. How will friction or air drag affect your design?

3. From your research and brainstorming, identify three possible design solutions to the challenge. Include diagrams of the designs.

4. Based upon the challenge, design criteria and research, select the solution that your team believes to be the best.

5. Identify materials needed.

6. Construct your zip line trolley system including the braking mechanism.

7. Conduct laboratory testing to evaluate your product and document the lab results with data tables and graphs.

8. Evaluate your product and make revisions to the product as needed.

The Presentation 1. Create a PowerPoint presentation summarizing your research and design that includes:

a. Title slide that contains a name for your zip line trolley system and the names of your team members.

b. Slides that document the Engineering Design Process including:

b.i. The challenge statement

b.ii. your web research,

2 b.iii. constraints for the project,

b.iv. the three design solutions to the challenge that you identified,

b.v. the design that your team chose as the best design solution to the challenge,

b.vi. the lab design tests and processes used to evaluate your design; provide evidence from your tests/results that support your explanations.

b.vii. the lab design results including data tables, data analysis, and graphs; ,

b.viii. any revisions to the design incorporated in your final product,

b.ix. explanations of how your design meets or does not meet the challenge.

2. Make a 5-6 minute team presentation of your PowerPoint in which every team member presents at least two slides.

3. Demonstrate your zip line trolley system in action.
