Repair of hydrounits-rational use of power resources and reduction of expenditures in a repair-serving orb of agriculture

Abstract

The theoretical sample piece for the exposition of movement of the forced simple harmonic motions of elastic mechanical systems in the viscous environment is analyzed. It is examined a case of excitation without influence of external forces immediately on the vibrating mass. Thus was considered that the forced force is affixed to a running end of an elastic element so that it moved according to the harmonic law. Expression of equivalent elastic force and the equivalent differential equation of a harmonic oscillating motion is received. Conditions of such oscillations in the conditions of the viscous environment are analyzed.
