The isolated period of a friction pendulum bearing depends principally on

  • A.the weight of the structure carried by the bearing
  • B.the coefficient of friction of the sliding interface
  • C.the number of bearings provided under the building
  • D.the radius of curvature of the sliding surface

Answer: D

The pendulum relation \( T = 2\pi\sqrt{R/g} \) involves the radius alone, so the period is independent of the mass carried. That independence is a considerable practical advantage, since it means the period does not change as the building's loading does.
