Abstract
Forced oscillations of a cylindrical drop of an inviscid liquid surrounded by another liquid and bounded in the axial direction by rigid planes are investigated.The system is affected by vibrations whose force is directed parallel to the axis of symmetry of the drop. The speed of motion of the contact line is proportional to the deviation of the contact angle from the value at which the drop is in equilibrium. Linear and nonlinear oscillations are considered. The conditions of the occurrence of resonance are determined.
