The Sandtrap

2. The Team

3. Introduction • Our goal was to build a mechanical “motor” to lift a 1 kg mass to a height of 1 m at around 10 sec. • Purchased materials included a mousetrap, toy car, ball, water bottles, nerf ball, and gallon jug. • Wood, water, sand, thread, duct tape, and nails are the other materials not purchased, but included in cost.

4. Process • We rev-up our toy car and place it on our platform to hit the ball. • The ball rolls down the ramp and hits the mousetrap. • The trap pulls down the gallon jug with weight. • The balance’s center of mass shifts to the water bottles of sand and falls off the balance. • The water bottle pulls the 1 kg weight to a height of 1 m.

5. Energy Conversions • Toy Car • Work to Kinetic Energy. • Ball • Gravitational Potential Energy to Kinetic Energy • Mousetrap • Elastic Potential Energy to Kinetic Energy • Bottles of sand • Gravitational Potential Energy to Kinetic Energy to finally lift 1 kg weight

6. Design Issues • Most of our time was spent with coming up with an ideal device to lift the weight. • Experimented several ways to balance both weights using our balance. • We struggled keeping the balance from falling off the platform.

7. Conclusions • Our project took about 4 hours to construct plus time planning beforehand. • We enjoyed working together and collaborating different ideas with each other. • We saved the best for last!
