This study presents the design, analysis, and fabrication of a lightweight go-kart prototype aimed at achieving optimal performance, safety, and cost effectiveness. The project focuses on key engineering aspects such as chassis design, steering geometry, braking system, and power transmission. A systematic approach was adopted to select suitable materials and components, ensuring structural integrity while minimizing weight. The fabrication process involved precision manufacturing and assembly techniques to meet design specifications. Performance evaluation of the go-kart was conducted based on parameters such as speed, stability, maneuverability, and braking efficiency. The results demonstrate that the developed go-kart meets the desired functional requirements and provides a practical understanding of automotive design principles. This project serves as an effective platform for applying theoretical knowledge to real-world mechanical engineering applications.
