🔍 Key Concepts

• Propeller balance and vibration when one blade is damaged or lighter than the others • How unbalanced rotating machinery affects bearings and supports • Typical symptoms (noise, vibration, wear) of a damaged propeller

💭 Think About

• If one blade loses a piece, how does that change the weight and hydrodynamic load compared to the other three blades? • What happens along the shaft line (bearings, couplings, hull) when something is rotating out of balance at high RPM? • Which of the listed effects are commonly associated with unbalanced or damaged propellers on real vessels?

✅ Before You Answer

• Confirm how an unbalanced propeller typically shows up first: vibration, noise, or bearing issues • Ask yourself whether all of the listed effects can logically follow from the same root cause (unbalance), or only some of them • Make sure you’re not overlooking any secondary effects (e.g., vibration leading to wear, and both producing noise)
