The document discusses the design of A-arms for a racing vehicle. It describes that the A-arms will use swept carbon fiber tubing with 6061 T6 aluminum rod ends and steel 4130 backups. Stress testing results are provided for the tire and connecting rod sides, showing safety factors above 2. Testing was performed on carbon fiber samples, with maximum and minimum yield strengths reported. The A-arm design will utilize a female joining method, a .007 inch bond gap, and 220 grit sandpaper for manufacturing ease and an estimated 6 kip yield strength. The project objectives also aim to design a new chassis, engine, and suspension setup to decrease weight and place in the top 10% of an international racing competition.
