Question 1 of 27070

In a steam turbine propulsion plant, the source of metal particles adhering to the magnets in the lube oil strainer is probably from the __________.

🔍 Key Concepts

• Magnetic materials vs. non‑magnetic materials in a turbine lube oil system • Which turbine parts are steel/iron (ferrous) and which are soft bearing metals like Babbitt • Where in a steam turbine plant you would expect the most gear tooth or surface wear that makes fine metal particles

💭 Think About

• First, decide which of the listed components are made mainly of ferrous (magnetic) metals and which are non‑ferrous (non‑magnetic). • Think about which part is most likely to produce fine steel wear particles that circulate in the lube oil, rather than large chunks or soft non‑magnetic debris. • Ask yourself: which component’s normal operation involves sliding/meshing of hard steel surfaces that could shed fine magnetic particles over time?

✅ Before You Answer

• Identify which options are definitely magnetic (steel/iron) and eliminate any that are normally non‑magnetic bearing metals like Babbitt. • Consider which component has continuous metal‑to‑metal contact under load that would create fine particles small enough to be trapped by the lube oil strainer magnets. • Before choosing, verify in your mind which part is most prone to normal wear that gives off magnetic dust, not just occasional damage fragments.
