Shoe Brake Assembly

Generate a 3D solid cylinder representing a brake drum. The cylinder has a radius of 100 mm and a thickness of 25 mm along the Z-axis. Center the cylinder at coordinates X = -50 mm, Y = 175 mm, Z = 0. Add a 20 mm diameter through-hole at the exact center for the shaft. Material appearance: Stainless Steel. Create a 3D rectangular bar for a mechanical lever. The bar has a total length of 540 mm, a height of 20 mm, and a thickness of 25 mm. Position the bar horizontally along the X-axis, starting from X = -70 mm and ending at X = 470 mm, centered at Y = 0. Create a 15 mm diameter through-hole at the origin (X = 0, Y = 0) acting as a pivot point. Material appearance: AISI 1020 Carbon Steel. Design a 3D rectangular block acting as a brake shoe. The base dimensions are 30 mm in length (X-axis), 75 mm in height (Y-axis), and 25 mm in thickness (Z-axis). Position the block so its vertical centerline is at X = -50 mm, and its base rests exactly on top of the lever. The top face of this block must have a concave cylindrical boolean cut with a radius of exactly 100 mm, centered at X = -50 mm and Y = 175 mm, to perfectly mate with the drum. Material appearance: Molded Fiberglass. Assemble a short shoe brake mechanism. Place a horizontal lever along the X-axis with a pivot hole at (0,0,0). Place a brake shoe block on top of the lever, centered at X = -50 mm, with a height of 75 mm. Place a drum cylinder with a 100 mm radius above the shoe, centered at X = -50 mm and Y = 175 mm. Ensure the concave top of the shoe perfectly matches the bottom curvature of the drum. The distance from the drum center to the shoe base is 175 mm. The lever extends 450 mm to the right of the pivot.
