The effective length factor for a column fixed at one end and free at the other is

  • A.One
  • B.One half
  • C.Zero point seven
  • D.Two

Answer: D

The cantilevered column is the weakest of the standard cases, with an effective length twice its actual length and a critical load one quarter of the pinned-pinned value. An undercarriage leg approximates this condition.
