A bearing metal should not have___________________?
Correct answer: B. Low thermal conductivity
- A. Enough plasticity
- B. Low thermal conductivity
- C. Low co-efficient of friction
- D. High toughness
Explanation
A bearing metal should conduct heat away from the bearing surface, so low thermal conductivity is undesirable. It should instead combine plasticity, toughness, low friction and adequate thermal conductivity.
