Zipline Engineering Challenge: Designing a Safe and Thrilling Descent

Join us in the Zipline Mathematics program as we tackle the challenge of creating a safe and exciting zipline carrier for Holly Mountain. This real-life problem involves designing a carrier that meets specific speed, safety, and usability criteria. Learn how to calculate speed, model with fishing lines and ping-pong balls, and apply the Engineering Design Process for a successful outcome.

Presentation Transcript

  1. Welcome to: • Zipline Mathematics • Focusing on: • STEM • Algebra I • Inquiry • Modeling

  2. Real-life Problem • Holly Mountain needs more revenue • Money from skiing in winter is not enough

  3. Board of Directors • They have approved the use of the slopes for zipline use in the summer

  4. Problem – Part 1 • Insurance company says the usual zipline equipment not safe enough

  5. Problem Part 2 • You must create a zipline carrier that: • attaches to the existing zipline • travels within a certain range of speed • provides a smooth, consistent descent • is safe • is easily used

  6. Modeling • Since we are not at the resort: • Fishing line represents zipline • Ping-pong ball represents a person • Minimal speed is 20 inches per second • Maximum speed is 60 inches per second

  7. How can we calculate speed? • What formulas could be helpful?

  8. distance = rate x time

  9. Low Cost is Good

  10. Engineering Design Process • What is it?

  12. Engineering Design Process

  13. A successful design… • meets the design criteria. • Is NOT too expensive.

  14. Criteria Reminder • You must create a zipline carrier that: • attaches to the existing zipline. • travels at least 20 inches/second. • travels no faster than 60 inches/second. • provides a smooth, consistent descent. • does not allow harm to ping-pong ball. • is easily used.
