🔍 Key Concepts

• Difference between bore, stroke, and swept volume in a cylinder • What inside diameter means in relation to a round cylinder • How piston displacement is calculated from basic engine dimensions

💭 Think About

• Which part of the cylinder-–length or width–-does the term in the question most likely refer to? • Which choices describe a dimension (a simple measurement) and which describe a calculated volume or movement? • If you were to measure this with a ruler or caliper, exactly what would you be measuring on the cylinder?

✅ Before You Answer

• Identify which options refer to a lineal measurement (distance) versus a volume (cubic measurement). • Make sure you can explain the difference between bore and stroke before choosing. • Verify in your mind how swept volume or displacement are calculated and what measurements they depend on.
