🔍 Key Concepts

• reduction gear tooth surfaces and what pitting/blue discoloration usually indicate • effects of overheating due to friction versus mechanical damage like misalignment • purpose of proper lubrication and warm‑up in gear trains

💭 Think About

• Ask what physical condition would most likely cause both high friction and high temperature at the tooth contact area until metal turns deep blue. • Compare what damage you would expect from misalignment (how would the contact pattern look?) versus from lack of oil film between teeth. • Consider which option would directly reduce the protective oil film between gear teeth and allow metal‑to‑metal contact at speed.

✅ Before You Answer

• Verify which condition leads to metal‑to‑metal contact over the tooth surface instead of on a small misaligned area. • Check which option most logically explains both pitting and deep blue discoloration (a temper color from heat). • Ensure the choice you select is the one most directly tied to the condition of the oil film between the gear teeth, not just operating speed by itself.
