The work is devoted to study of the effective tool of organization of educational creative activity of the students — professionally — guided problem situation offered the trainee as of an Olympiad task. In clause the integrated classification of Olympiad tasks is given, the basic stages of their development are considered; the specific features ofpreparation of tasks for preparatory ...

In this article we give the description of the principles of studying the distribution of acceleration of wheel points. Cases of even and non even rolldig on the plane and cylindrical surfaces are also examined. It is shown that in all the cases of movement the instantaneous centers of accelerations are determined only by geometrical parameters of a wheel and of a rolling surface. ...

There are considered variants ofapplication of ANSYS program product at holding occupations for the students studying courses of mechanics under the abbrex’iated course. The opportunities of the program promoting an enhance of student s knowledge are shown by the example ofproblem solving about a bending of a beam with opened profile, shell stability, a deformation of a reinforced ...

The experience of using information technologies at the Department of Materials Resistance, Building Mechanics and Metal Constructions of Polotsk State University in teaching the course «Numerical methods of construction tasks solution» to the second-year students with the speciality «Civil and Industrial Engineering» is considered.

То а choice of the generalized coordinates of machines with impulsive change of working loadings. Traditionally the rate of the theory of mechanisms and machines is based on researches of mechanisms in function of the generalized coordinates which change in regular intervals. At impulsive distribution of technological loadings it results in the big errors of calculations. More ...

The report presents the curriculum of the following course «Physics of failure and machine reliability fundamental», and also given the examples of the applied uses of lineir mechanics of destruction.

When the principle of Dalambert is presented to students, the thought of duality in strength is implanted in them. The principle of Dalambert is deduced from the Second Low of Newton. In mechanical systems inertial loading are introduced for specific cases of the solid body movement.

The model of non-straight method of pH factor measurement in acid-alkali mixture based on measurement of material quantity in separate components of mixture is described. Mathematical model allows us to calculate tolerable meanings of metrological characteristics of measurement channels and technical cha?-acteristics of the object of measurement (i. e. volumes and concentrations ...

The methodical aspects of the teaching of the mechanical problems with imaginary time are discussed on the two examples (WKB approximation and sound absorption at high frequency).

Appearing of chaos at an propagation of waves in the determined heterogeneous media to invistigation in the general case yet it is not possible. The ray method allows to reduce partial differential equation to the ordinary nonlinear differential equations, to which investigation it is possible to apply methods of nonlinear dynamic of systems. The closed systems of the equations ...
