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 the report conditions of driving force initiation of mobile machine wheel are analysed. It is stated that the given force emerges in consequence of correlation of processes in contact zone with base and in pivot zone as a result of outside potential force activity. On the basis of strict compliance with the fundamental laws it is found that outside potential force activity is ...

This paper is а brief review of some interesting applications of the computers replaced in the theoretical and applied mechanics. The validity of analytical approach has been by numerical solutions in the various software: «МАТНЕМАТІСА». «МАТЪАВ», MECHANICAL SYSTEMS», «WORKING MODEL», etc. This software is used to find numerical solutions of the equations ofmotion and to present ...

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 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.

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 ...

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 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 ...

Some probability problems in an applied mechanics of the random vibration are discussed.

1п this work the procedure of measurement of charge carrier parameters in non-homogeneous object of measurement — monocrystal indium arsenide with inversion channels on the surface is proposed. Analysis that was held shows that using of integral characteristic of formation process of complex integral galvanomagnet measurement signal in selected object allows us to determinate ...
