An analysis of the state of stresses generated by torsion in twisted non-circular bars Abstract One of the main problems that must be solved in the design of the machine components stressed in torsion is to establish their optimum shapes and dimensions in order to resist for a given twisting load. Also, in the case […]
History of the model of the atom The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”.

Get startedThe Motion of a Mass Spring System The example of a mass attached to the end of a spring is a powerful tool in physics due to the fact that it is analogous to many physical phenomena. To be able to use this example to elegantly describe other more complex systems it is crucial to […]
The variation of light intensity with distance; namely the inverse square law of light intensity with distance. Background Theory Light emitted from any kind of source, e.g. the sun, a light bulb, is a form of energy. Everyday problems such as lighting required for various forms of labouring or street illumination, require one to able […]
