Innovative Device for Lifting Weight in Under Ten Seconds

DESCRIPTION

This project, "Pulling Your Weight!", created by Matthew Austin, Martin Binhammer, Garret Welch, and Trevor Willis, aimed to design a device that could lift a one-kilogram weight one meter in about ten seconds. Utilizing various materials including mousetraps, wood, and a drill, the device operates by releasing a marble that triggers a series of actions leading to the weight being lifted. The project highlights the conservation of energy principles and faced significant construction challenges, taking ten hours and costing $19 to complete.

  1. Pulling Your Weight!  BY: Matthew Austin Martin Binhammer Garret Welch Trevor Willis

  2. Introduction • The goal of this project was to construct a device using ideas learned in EF 151 this year to lift a one kilogram weight for a length of one meter as close to ten seconds as possible. • The materials: a drill, two mousetraps , pieces of wood, a genetics text book, cardboard, nails, duct tape, and marbles.

  3. Overview of Design • The device begins with a marble falling down a ramp, hitting a lever, and releasing another marble. • The second marble sets off the mousetrap pulling away the support holding the book up. • The book falls on drill trigger pulling up the weight. • The Drill is turned off when a carabineer sets off the second mousetrap cutting the circuit from the drill to the battery. • Task complete!

  4. Conservation of Stored Energy • Marble – Gravitational potential energy before released later turned into kinetic energy. • Spring in both mousetraps- Stored potential due to tension in the spring. • Drill- Electric potential energy in the batteries and motor. • Book- Gravitational potential energy before support is pulled later turned into kinetic energy .

  5. Construction Issues/Conclusion • A major issue was how to stop the drill once the weight went one meter in ten seconds. • Another issue was getting the book to fall correctly on the trigger which would start the drill. • 10 hours of work was put in on this project. • Materials cost $19
