🔍 Key Concepts

• Critical speed of rotating machinery (main turbine, main engine, etc.) • Dangers of severe vibration: damage to bearings, blades, and alignment • Standard engineering practice when you hit a vibration zone while changing speed

💭 Think About

• When you feel severe vibration while increasing speed, what is your first priority: keeping schedule or protecting the machinery? • Is it safer to push harder through a vibration range, stay in it, or move away from it in a controlled, cautious way? • What action allows you to quickly reduce the stress on the turbine while still maintaining control and the ability to respond to future bells?

✅ Before You Answer

• Verify which options would prolong operation at the vibrating speed range and therefore increase damage risk • Check which choice best reflects a cautious, protective response that still keeps the plant available if needed • Eliminate any option that suggests remaining at or increasing a speed that is already causing severe vibration
