Presentation Transcript

  1. Bucket Vortex

  2. Team Members • Andrew Milstead • Justin Shelton • Nate Best • Josh McCullough

  3. Design • Uses blue plastic tubing wrapped inside a bucket. • Ball bearing descends down the tubing at a constant acceleration. • Tubing is zip-tied through holes in bucket.

  4. Stored Energy • Stored energy = mgh • Stored energy is the height • gravity • mass • Example: (10 g ball) • (.01kg)(9.81m/s2)(.441m)= 0.0433 joules

  5. Design/ Construction Issues • Deciding on a final product. • Time management • Finding materials to match our ideas

  6. Materials/ Tools • Bucket • Blue plastic rigid tubing • Red zip-ties • Ball bearing • Drill • Exacto knife • Duct tape • Tape measurer

  7. Conclusion • As long as the ball bearing has a slight initial velocity the sphere will roll all the way down the vortex. This is also possible due to the exact differences in height as the bearing makes a revolution around the bucket.
