Abstract

Proposed is a design for an improved geometry triathlon bike that orients the posture of the tri-athlete in a standing position during the cycling stage of a triathlon. This posture was found to be optimal for reducing muscular fatigue in the swimming and running sub-events of a triathlon. Presented is a design solution that details the steps of the design process including handlebar design, frame geometry, material and tubing size analysis, and a stability analysis of the bike modeled as a second order differential equation.

Description

Created in fulfillment of the course requirements for ENGG*3100 Engineering and Design III. This course combines the knowledge gained in the advanced engineering and basic science courses with the design skills taught in ENGG*1100 and ENGG*2100 in solving open-ended problems. These problems are related to the student's major. Additional design tools are presented, including model simulation, sensitivity analysis, linear programming, knowledge-based systems and computer programming. Complementing these tools are discussions on writing and public speaking techniques, codes, safety issues, environmental assessment and professional management. These topics are taught with the consideration of available resources and cost.
