Elastic deformation statically of uncertain beam system a console - basic a rod experimentally is investigated at an operation on a console of a disrtibuted statistical load and shock waves of the graduated profile. The influence of a reinforcement of a beam type to deformation of the elements of boards as a cantilever beam is established. Is investigated dynamics of rigid and elastic cylinders located about the rigid flat boundary of fluid, and which under any angle the acoustic wave drops. Driving the cylinder under an operation of radiation forces is investigated which are formed by an interference field primary both reflected from the boundary and cylinder of acoustic waves. The operation of radiation forces on the cylinder in an assotiation from an angle of incidence of an acoustic wave, wavelength and distance of the cylinder from the boundary is appreciated. The regularities of distribution of waves along the flat boundary of the unit beforehand of intense elastic stratum are carried out which c ooperates with a stratum of viscous fluid. The dispersing relations are obtained and the influence of viscosity, denseness, compressibility of fluid and initial voltages on phase velocities and damping factors of waves is investigated. The numerical methods of problem solving about distribution of waves in stratified skew fields with initial voltages are developed
