🔍 Key Concepts

• How mechanical pressure gauges work (Bourdon tube, linkage, gears, pointer) • Common causes of a sluggish pointer (friction, dirt, sticking parts vs. simple misalignment) • Why adding force or bending parts can damage calibration instead of fixing the problem

💭 Think About

• Which part of the gauge could realistically slow down its movement when pressure changes: the pointer, the spring, or the moving gears/linkage? • Which action is more like a temporary trick vs. a proper repair that restores smooth mechanical motion? • Would adding a lubricant to a delicate spring make its motion more precise, or could it interfere with its designed elasticity and response?

✅ Before You Answer

• Eliminate any choice that risks permanently bending or deforming calibrated parts (like the needle or spring). • Focus on the option that reduces friction or sticking in the moving mechanism rather than just forcing it to move. • Avoid any action that a trained technician would consider a shortcut or risky field fix instead of a true repair.
