Abstract (2. Language): 
The paper deals with the dynamics of discrete-continuous systems longitudinally deformed. These systems consist of elastic elements connected by means of rigid bodies. In the discussion a wave method using the solution of the d’Alembert type is applied, what leads to equations with a retarded argument. After a general information concerning the wave approach, detailed considerations are done for a system consisting of three rods and two rigid bodies. Rods in the system have variable cross-sections and in numerical calculations their effect on rods’ displacements is investigated.
