The over speed trip device installed in some diesel engines is automatically actuated by __________.

Question 1 of 27070

The over speed trip device installed in some diesel engines is automatically actuated by __________.

🔍 Key Concepts

• Over speed trip device purpose in diesel engines • How rotating speed can be sensed automatically in engine governors and safety devices • Difference between forces created by rotation vs. springs, hydraulics, or linkages

💭 Think About

• Ask yourself: which of these options changes automatically as the shaft RPM increases, without anyone adjusting it? • Which force or mechanism is commonly used in engine governors to sense and react to excessive rotational speed? • Which option directly depends on rotational motion, rather than needing an external actuator or fluid supply?

✅ Before You Answer

• Identify what physical effect increases with rotational speed (RPM) and can move weights or a collar outward • Eliminate options that require an external power source or manual actuation rather than speed itself • Recall that many classic engine governors and trips use a device whose force is proportional to mass × radius × (RPM²)
