Which of the devices listed is installed on a diesel engine to isolate some of the crankshaft vibrations caused by rotational and reciprocating forces?

🔍 Key Concepts

• Crankshaft vibrations and what causes them in a diesel engine • Purpose of a torsional vibration control device • Difference between power-transmission components (gears, clutches) and vibration-isolation components

💭 Think About

• Ask yourself: which option is specifically designed to absorb or reduce twisting (torsional) vibrations in a rotating shaft, rather than just transmitting power? • Think about diesel engines: what component is often mounted at the end of the crankshaft to smooth out irregular rotation? • Which listed devices are mainly used for changing speed/torque or engaging/disengaging drive, and which one is for vibration damping?

✅ Before You Answer

• Verify which device is directly connected to the crankshaft specifically to reduce vibration, not to change gear ratios or engage/disengage power. • Check which options are primarily power-transmission devices (gears, clutches) rather than vibration-damping devices. • Confirm which device is associated with controlling torsional (twisting) vibration in rotating machinery.
