Questions and Answers

What material is an elastomeric bearing made of?

  • Synthetic rubber only
  • Plastic
  • Both natural and synthetic rubber (correct)
  • Natural rubber only

    • What happens when an elastomeric bearing is subjected to loads within its elastic range?

  • It becomes brittle
  • It regains its initial shape and dimension (correct)
  • It deforms irreversibly
  • It melts

    • What is the purpose of reinforcing elastomeric bearings with horizontal steel plates under high vertical loads?

  • To soften the rubber
  • To increase the vertical deformation of the rubber
