The prompt
Design a 3-chamber exhaust muffler for 300cc engine with these specifications: OVERALL: 380mm length, 110mm diameter cylindrical shell, 2mm wall thickness CHAMBERS (3 total): - Chamber 1: 80mm length (inlet side) - Chamber 2: 140mm length (middle, filled with rock wool insulation) - Chamber 3: 80mm length (outlet side) PIPES: - Inlet pipe: 30mm diameter, enters Chamber 1 - Outlet pipe: 30mm diameter, exits Chamber 3 - Central perforated tube: 30mm diameter, 300mm long, runs through all chambers * Perforations: 6mm holes, 15mm spacing, 3 rows, only in middle 250mm BAFFLES (3 internal plates): - Diameter: 106mm, thickness: 2mm - Each has 30mm center hole for tube passage - Plate 1: at 50mm from inlet end - Plate 2: at 130mm from inlet end (welded to central tube) - Plate 3: at 270mm from inlet end CREATE THESE VIEWS: 1. Full longitudinal section showing all internals 2. Cross-section through Chamber 2 (showing insulation) 3. Cross-section through Chamber 1 or 3 (empty chamber) 4. Detail of perforated tube with hole pattern 5. Detail of baffle plates 6. Bill of materials Include all dimensions, metric units, and basic manufacturing notes.
