Jerk limiting is particularly important on

  • A.lifts and cranes carrying people or liquids
  • B.centrifugal fans running continuously at fixed speed
  • C.pumps delivering into a constant static head
  • D.conveyors carrying dry uniform granular material

Answer: A

Correct answer: lifts and cranes carrying people or liquids

A step change in acceleration is felt directly by a passenger and sets a suspended load swinging or a liquid surface sloshing. Jerk limiting is therefore a comfort and safety requirement rather than a refinement, and lift specifications state jerk limits explicitly alongside acceleration.
