🔍 Key Concepts

• Centrifugal brake function in mechanical systems • How lifeboat winch drums control gravity lowering of boats • Difference between stopping/holding a load vs controlling speed during movement

💭 Think About

• Think about what happens if a lifeboat is being lowered by gravity and starts to go too fast—what kind of device would help manage that? • Which option describes a function that uses spinning motion (centrifugal force) to regulate something, rather than simply locking or holding it? • Ask yourself: is this device mainly a backup stop/holding device, or is it a regulating/speed-controlling device during lowering?

✅ Before You Answer

• Identify which choices describe holding or stopping the boat versus regulating speed while moving. • Recall that a centrifugal mechanism reacts to rotational speed—so which option connects most directly to that idea? • Verify which option refers specifically to gravity lowering operations rather than electrical or manual braking failure.
