2. Overview of Design Wood platform and towers. Spiral tube using gravity. PVC tube. Newton’s Cradle Stick with a needle. Balloon with weight inside Mouse Trap Bottle Opener that plays “Rocky Top” Costs: Bottle opener: $10 Needles: $4 Everything Else: FREE

3. 1.PVC Pipe Spinning down Spiral 2.Steel ball rolling down slope 3.Ball starting a Newton’s Cradle 4.Stick with needle on end falling onto balloon 5.Balloon popping, releasing pellets. 6.Pellets springing a mouse trap 7. Mouse trap connects batteries to speaker, beginning “Rocky Top” 1 2 3 4 5 6 & 7

4.  Hollow Cylinder (Angular Momentum) L=I ω  Ball Rolling down pipe ramp (COE) mgh=(1/2)mv² + (1/2)I ω ²  Newton’s Cradle (Collision/Linear momentum) m 1 v 1 + m 2 v 2 = m 1 v 1 ’ + m 2 v 2 ’  Stick Balancing (Center of Mass) R = m 1 r 1 + m 2 r 2… m 1 + m 2…  Trap Springing (Torque/Rotational Energy) τ = Frsin( θ )

5.  Spiral would not cooperate, had to make many different types.  Stick would not pop balloons with nails, had to go buy actual needles.  Could not find a suitable electronic device for the trap to set off.  Once we got the piece we could not get the metal pieces to connect correctly

6.  We visually learned the applications from our lectures from the past four modules  We learned that time management is a key to a successful group project.  It was a fun, but intellectually tiring project.
