Apparatus required: Laboratory model Table. Theory: The shaking or Wilfiey table consist of a substantially plane surface (the deck), inclined slightly from the horizontal and shaken with an asymmetrical motion in the direction of the long axis. Asymmetrical motion means, the stroke of the table is faster in one direction and slower in opposite direction. Usually the back- stroke is ...
