🔍 Key Concepts

• Noise and vibration control in passenger ship design • Difference between rigid mounting and resilient (flexible) mounting of machinery • Purpose and effect of flexible couplings in a propulsion shaft line

💭 Think About

• Think about how vibrations from the main engine get transmitted into the ship’s hull and passenger spaces. Which type of mounting would tend to isolate vibration instead of passing it straight through? • What role do flexible couplings play between the engine and the shaft? Would they increase or decrease the transmission of vibration and noise? • Passenger comfort is a high priority. Imagine riding above the machinery space: which combination of mounting and coupling would most likely make that space quieter and smoother?

✅ Before You Answer

• Identify which options use resilient (flexible) mounting versus rigid bolting of the machinery to the structure. • Check which choices use flexible couplings and think about how they affect vibration transmission in the shaft line. • Eliminate any option where both the mounting and the power transmission method would tend to directly transmit vibration into the hull without isolation.
