Adhesive Force of an oscillating surface

  1. Aug 5, 2011 #1

    An oscillating plate, something like this:
    has an adhesive surface.

    Suppose a particle is stuck to the plate, what is the Adhesive Force on the particle over time [equation]

    I know that the break-off force is equal to 10N
    But the adhesive force should vary with the tensile force acting on it, so it must be less than 10N at some time during the periodic oscillation...

    I thought it was equal to normal force experienced by the particle [-mass*(acceleration due to periodic oscillation - gravity)] but would that mean it would double the weight?!!
