🔍 Key Concepts

• Identify what component the handle labeled B is mechanically connected to in the diagram (governor, overspeed trip, lube oil system, or pinion/turning gear). • Recall how a turbine overspeed trip is normally reset versus how a governor is bypassed or placed in manual control. • Consider how lube oil is normally supplied to the manifold and bearings on a ship service turbo‑generator (electric pump vs. any hand‑operated device).

💭 Think About

• Look at where motion from handle B is transmitted: does it move linkages toward the governor, toward the trip mechanism on the steam valve, or toward the oil pump/manifold? • Ask yourself which of the listed functions would realistically be done by a small hand lever during normal start‑up or after a trip: which ones would require more power or a different mechanism? • Compare the location of the overspeed trip parts (near the main steam valve) with the location of handle B—does the drawing show a direct connection or an indirect path?

✅ Before You Answer

• Verify exactly which labeled parts are directly connected by solid mechanical linkages to handle B. • Confirm whether any line from handle B goes into the lube oil sump or manifold (if not, eliminate that choice). • Check the right‑hand side of the drawing for the overspeed trip and steam stop/operating valves and see how their reset or trip linkage is shown relative to handle B.
