Introduction • Derek Naylor – Team Leader • Ashton Litterell -Technical Analysis • Ling-Hsiao Chang - Budget • Jacob Melton - Construction/Model Design

Process – Step 1 Need: Handicap white water rafts Problem: To establish a safe and fiscally realistic foundation for a person with a handicap to successfully white water raft Success: * Low Cost * Safe * Comfortable * Ergonomic Constraints: *Getting on and off the raft *Trunk support *Leg Brace *Getting momentum *Comfort *Price *Customization of the seat *Compatibility of all products to withstand environmental cond

Process – Step 2 Resources: Lemley, Evan Dr., (Personal Communication) Bowan, Dr., (Personal Communication, several dates in February) Vick, Jason (Personal Communication, February 21, 2007)

Design #1

Design #2

Required Skills • Physics – General Physics, Strength of Materials • Mathematics – Geometry • Engineering – Coming together to solve the problem

Materials for Raft 1 • • 72"W x 107"L • • Modular Anodized Aluminum Frame • • 4 - 107" Side Rails • • 2 - Yokes • • 2 - Foot Bars • • 1 - Cross Bar • • 2 - Seat Bars • • 2 - High Back Seats • • 1 - Pair of Oar Mounts • • 2 - 9' Straps • • 4 - Strap Slides • (Est. Price: $1,119.95)

Materials for Raft 2 • • 72"W x 120"L • • Weight: 120" is 122lbs. • • Modular Anodized Aluminum Frame • • 4 - 120" Side Rails • • 2 - Yokes • • 2 - Foot Bars • • 2 - Cross Bars • • 1 - Seat Bar • • 1 - High Back Seat • • 1 - Cooler Mount • • 1 - Pair of Oar Mounts • • 2 - 9' Straps • • 4 - Strap Slides • (Est. Price: $1,059.95)

Results • Undefined due to lack of funds

Conclusion • With significant research, it is logical to theorize that the raft would have met the needs of an aspiring and handicap white water rafter.
