Engineers

Introduction -The goal of this project was to make a rollercoaster that lasted 15 seconds and fit inside a.5 x.5 x.5 meter box. -To do this we attached clear plastic piping to a wooden frame to make a track for a bb to run down.

Construction -Constructed the 0.5 x 0.5 x 0.5 meter frame out of 2 x 2 x 28 inch lumber and nails -Heated the rubber tubing with a blow dryer to straighten out kinks -Fastened tubing to frame using zip ties -Covered in tin foil to make it robo-licious

Calculations -The distance from the top of the coaster to the ground is.6223 meters. -Given that the ball has a mass of.3421 grams we calculated that the initial potential energy of the coaster is g*m 2 /s 2. -Also because the ball ends with no potential or kinetic energy it loses g*m 2 /s 2 of energy through friction and other losses throughout the coaster.

Conclusion -One of the major problems we ran into was that we had trouble making the coaster last 15 seconds, so we had to keep the ball moving as slowly as possible without it stopping. -In the end we had to attach a dish for the ball to spiral down to make the coaster last the required 15 seconds
