Which of the following couplings or clutches would be able to prevent the transmission of torsional vibrations from an engine to a reduction gear?

🔍 Key Concepts

• Torsional vibration and how it travels through a drive train • The difference between rigid (solid) couplings and flexible / fluid / elastic couplings • How slip or cushioning in a coupling affects vibration transmission

💭 Think About

• Which of these devices allows some slip, cushioning, or damping between the engine and the reduction gear, instead of locking them together as one solid rotating unit? • Think about which option would smooth out sudden changes in torque, and which ones would pass those changes directly through. • For each choice, ask: Is there an elastic element (air, fluid, rubber) that can absorb or damp torsional shocks?

✅ Before You Answer

• Identify which options are essentially rigid / direct-drive (little or no damping). • Identify which options have a compressible or shearable medium (like air, oil, or rubber) that can absorb vibration. • Confirm that the selected option is commonly used to isolate or damp torsional vibrations in marine propulsion systems.
