The prompt
Create a steel rectangular bar. Dimensions: Length = 400 mm Width = 40 mm Height = 25 mm On the top face, create a centered longitudinal channel that exactly fits a standard bicycle roller chain (ANSI #40 or 1/2" x 1/8"). The bicycle chain is permanently welded inside the channel along the entire length of the bar. The chain must remain a real bicycle roller chain with rollers, pins, inner plates and outer plates. The chain is fixed to the bar and moves together with the bar. Do not generate any sprockets. Do not generate shafts. Do not generate bearings. Generate only the steel bar with the welded bicycle chain.
