Match the property with the component that provides it in a lead rubber bearing.

1. Vertical stiffness   2. Horizontal flexibility   3. Energy dissipation

P. Rubber layers in shear   Q. Lead core   R. Steel shims restraining the rubber

  • A.1-Q, 2-P, 3-R
  • B.1-R, 2-Q, 3-P
  • C.1-R, 2-P, 3-Q
  • D.1-P, 2-R, 3-Q

Answer: C

The shims stop the rubber bulging and so make the bearing stiff vertically, the rubber shears freely in the horizontal plane, and the lead core yields to absorb energy. One component doing three jobs is what makes the bearing so compact.
