Methods of analysis of statically determined mechanical systems are described in the thesis submitted to define contact reactions without balance conditions compiling. Beam models are considered as a method basis. It promotes students long-term learning and engineering intuition development.

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. ...
