Mechanical engineering

 Interesting elasticity, especially spring elasticity Here we have four examples of elastic behaviour in mechanics. We suppose absolutely rigid the ball, the wall and the construction. Reference system is outside – connected with “paper”. See images...

Mechanics and Technology

Thermodynamics  – mechanics of chaotic behaviour of particles The basis of thermodynamics and indeed of the whole world is chaos. Chaos in a closed space. Chaos of moving particles, molecules, atoms. This chaos can be converted into mechanical work by the...

Physics of energy conversion

Considerations on the subject of chaos A few phrases at the beginning…in the beginning was chaos …. from chaos arose order ….. or chaos is the basis for the principle of self-organization which explains the present universe with its complex structures … etc....

Measurement and Control (Regulation)

Measurements, probability and statistics Where is the right value N? We are unable to measure directly right value N of something – diameters of balls or anything else. We are only able to measure a certain amount of values that, in effect, when plotted,...
