  1. TEAM BUNGEE Cameron James Jacob Camp Ronnie Harris Jason McCants EMAP 2006 University of Alabama College of Engineering

  2. Introduction • Chemical & Biological Engineering Group • Labs by Chris Brazel, PhD and Sandra Wood, MSE • Chamber Project Assignment • Design bungee jump attraction for Lake Nicol • Bungee Jump • Physical & Mathematical Principles • Material & Design Considerations for Jump Safety • Marketing Approach • Economics & Feasibility EMAP Team Bungee 7/19/06

  3. Bungee Math – 2 Basic Principles 1) Cord Motion = spring = Hooke’s Law (1660) Cord deformation is proportional to load Force = k x k = spring constant ; x = length 2) Cord Elasticity = Young’s Modulus (1807) Ability of cord to regain its original length Elastic Modulus = Stress/Strain Stress = Load / Cross sectional Area Strain = Extension / Length EMAP Team Bungee 7/19/06

  4. Example Mathematics • Unstretched cord 20 meters long with an elasticity of 50% and a spring constant of 20 Newtons/meter can hold what force? Force = (20 N/m) (10 m) = 200 Newtons • Unstretched cord 45 meters long with 75% elasticity holding a 350N force has what spring constant? 350 N/m= (k) (33.75 m) so k=10.37 N/m EMAP Team Bungee 7/19/06

  5. Bungee Jump Cord - Materials & Design • Commercial bungee cord used • Designed to user’s standards • Elastic strand with rubber core & braided fabric covering • 0.62inch = 1.6cm diameter • Cord weighs 14 lbs / 100 ft • Stretch factor of 100 to 125% • Supports 250-350lbs @ 100% • 500-600 jumps/cord typical EMAP Team Bungee 7/19/06

  6. Bungee Jump • Typical Tower Design • Anchor into rock cliff or a stand alone structure • 100-150 feet high • “Walk the Plank” concept jump over the water • Day and night jumps offered EMAP Team Bungee 7/19/06

  7. Regulations and Guidelines • North American Bungee Association (NABA) • Operate with a safety factor of 5 • cord and related apparatus designed to carry up to 5 times the max allowed passenger weight • Certified jump masters & trained operators • 4 daily inspections • Allow 5 minutes between jumps for cord to return to original length • Bungee cords replaced weekly (500-600 jumps) EMAP Team Bungee 7/19/06

  8. Safety & Liability Three-way safety system: • Full body harness • Ankle strap system • Contractor Quality Safety Net Limitations • Minimum Age – 18 years • 16yr with parent signature • Jumpers sign release form • Weight range: 100-300 lbs • Maximum + 3 Gs EMAP Team Bungee 7/19/06

  9. Into the “JAWS” of Death • Additional Thrill Factor • Jumper ”walking the plank” sees shark fins circling below • Safety net attached to underwater shark apparatus • “JAWS” shark emerges to thrill jumper or spectators EMAP Team Bungee 7/19/06

  10. Marketing • Population of the city of Tuscaloosa • 80,000 without UA students • 100,000 with UA students (Aug – May) • Add 50,000 for home football games • University & Sports Enthusiasts 18-65 yrs • Target audience ~65% of Tuscaloosa and State of Alabama population EMAP Team Bungee 7/19/06

  11. Jump Pricing • $35 per jump • $15 for “I Walked the Plank”shirt • $10 for a photo of your jump • $50 package = jump, shirt, & photo • Group rates for university & student organizations (EMAP, BamaBound, etc) EMAP Team Bungee 7/19/06

  12. “The Plank ” • Open-air restaurant & bar overlooking water • Nautical/Pirate Theme • Comparable to Treasure Island in Panama City, FL • Bungee jump visible from restaurant • Separate mock floating ship serves as spectator platform or souvenir/gift shop • “Treasure Island” Miniature Golf Course EMAP Team Bungee 7/19/06

  13. THE PIRATE “ALABAMA” http://www.sonofthesouth.net/leeFoundation/civil-war/1862/pirate-alabama.htm EMAP Team Bungee 7/19/06

  14. Fixed/Startup Costs • Cantilever Tower $95,000 • Tower Foundation $10,000 • Installation $6,000 • Tower Operating Equipment $9,000 • Permits and Liability Insurance $30,000 • Annual Renewal $1,000 • Quarterly Inspection $500 (x4) • License Fee $5,000 • Safety Equipment $2,000 • Mechanical Shark Apparatus $15,000 Estimated Total = $175,000 EMAP Team Bungee 7/19/06

  15. Weekly Operational Costs • Staff (2 shifts, 12 hours/day, 4 days/week) • Jump Master $1,000 • Jump Operator $500 • Landing/Recovery Operator $350 • Registration/Gift Shop Clerk $350 • Daily Maintenance / Inspection $350 • Replacement Cords (1/week) $1,000 • Power Consumption (motors, flood lights, etc) $100 Estimated Total = $4,000 EMAP Team Bungee 7/19/06

  16. In Review… • Bungee jump could be a stand-alone project operational in 3-4 months • Can be located on lake, riverfront or land • Will attract the student population of Tuscaloosa, surrounding county & state • Great marketing scheme for the city • 1862 Rebel Pirate Ship “Alabama” • “The Plank” Restaurant & Bar • ”I Walked The Plank” Souvenirs • “Treasure Island” Putt-Putt Golf EMAP Team Bungee 7/19/06

  17. I Walked the Plank Team Bungee Any Questions? EMAP Team Bungee 7/19/06
