Q

Diesel engine crankshaft deflection readings are generally taken at four crank positions. Good engineering practice requires the deflection gage or indicator to be __________.

🔍 Key Concepts

• crankshaft deflection readings and why consistency matters • how indicator placement affects measurement accuracy • the effect of moving or resetting instruments between measurements

💭 Think About

• Which option would give you the most consistent basis for comparing four readings taken at different crank positions? • If you are looking for small changes in deflection, how could extra handling or repositioning of the gauge affect your results? • Think about what engineers want to keep the same (constant) and what they deliberately change when taking a set of comparative readings.

✅ Before You Answer

• Verify which choice best reduces human or setup error during the series of readings. • Check which practice would keep the reference conditions identical for each crank position. • Consider which action might introduce variation not caused by the crankshaft itself.
