Why is safety-wiring, or lock wiring of gas turbine parts required?

🔍 Key Concepts

• Purpose of safety/lock wire on fasteners in high‑vibration machinery like gas turbines • Difference between holding torque vs. stopping movement if torque is lost • What can happen to bolts/nuts in a turbine if they start to back off or loosen

💭 Think About

• Think about what happens first when a nut or bolt starts to loosen in a vibrating gas turbine—what is the immediate mechanical danger? • Is safety wire meant to keep the fastener tight forever, or to make sure parts don’t separate if the tightness starts to be lost? • Which choices describe functions that safety wire is actually designed to do, versus maintenance tasks that are handled by other procedures (like lubrication or corrosion control)?

✅ Before You Answer

• Identify which option directly relates to physical movement or separation of fasteners/parts under vibration. • Eliminate any answers that are mainly about chemical or fluid properties (like rust or oil). • Ask: which choice best matches the idea that the wire is a backup restraint if a fastener starts to loosen?
