The prompt
Design a reinforced lower suspension A-arm for an independent double-wishbone system. Total length from chassis mounts to wheel hub: 550mm. Wide base spacing at the chassis: 400mm. Fabricated from 32mm structural steel round tubing with a 3mm wall thickness. The apex of the A-arm must feature a flat mounting tab for a suspension joint. Include a U-shaped reinforcement clevis bracket for a 420mm ATV shock absorber, positioned exactly 200mm from the chassis pivot axis.
