What is the displacement for a Bore of 1.75 inches and a Stroke of 3.25 inches?

What is the displacement for a Bore of 1.75 inches and a Stroke of 3.25 inches?

• A. 6 cubic inches
• B. 7 cubic inches
• C. 8 cubic inches
• D. 10 cubic inches

Answer: (C)

To find the displacement of an engine, you can use the formula: Displacement = (π/4) × Bore² × Stroke × Number of Cylinders. In this case, if we are considering a single-cylinder engine, we can simplify the calculation. 1. Convert the bore and stroke from inches to the appropriate values in the formula: - Bore (diameter) = 1.75 inches - Stroke (length) = 3.25 inches 2. Calculate Bore²: - Bore² = (1.75 inches)² = 3.0625 square inches. 3. Multiply by Stroke: - Bore² × Stroke = 3.0625 square inches × 3.25 inches = 9.953125 cubic inches. 4. Now apply the π/4 factor for the cylindrical calculation: - Displacement = (π/4) × 9.953125 cubic inches. 5. Approximating π as about 3.14, the calculation becomes: - (3.14 / 4) × 9.953125 = 0.785 × 9.953125 ≈ 7.81 cubic inches. This value rounds to
