The article deals with the de termination of the basic inte gral characteristics of the objects as are the volume, mass, centre of gr avity and the moment of inertia. The article mentions the problems, which originate at the calculation of these characteristics for the parts with difficult shapes. The utilization of CAD/CAM is one of the possibilities which can be used at the solution of this problem. The specification of these characteristics is necessary at the sugges tion or dimensioning of machine parts and al...

The article deals with the kinematics analys is of crank mechanism realized by three methods followed by comparison of achieved results. The crank mechanism is the most commonly used mechanism in practice; it is the part of the various machines and almost every car. It belongs to the fundamental mechanisms whereon the kinematic characteristics of mechanism are investigated by students on FMT TU KoЕЎice with seat in PreЕЎov within the scope of Technical mechanics lessons. Ar ticle hints as the utilization of suitab...
