Modern cars and speed

Although having sporting a modern car very often remains just a dream for motorists, people with such cars more often appear on Polish roads. I must admit that this car really pose a huge threat to all road users. In sports cars do not feel the speed, and special arrangements are responsible for the fact that you can achieve really high speed driving. It is not only dangerous, but in some cases, even deadly. Despite the passionate driving fast sports car is not lacking, and for some of them the adrenaline during such driving is one of the most important experiences, so that they feel really good.


Electric motor - history

Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s.2 The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Amp?re's force law, was discovered later by André-Marie Amp?re in 1820. The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire.3 This motor is often demonstrated in physics experiments, brine substituting for toxic mercury. Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century.

In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings

It is worth to test the car before buying it?

Currently, virtually all car showrooms offer the opportunity to test the car, motorcycle or other vehicle before buying. It is a good idea, because we feel as though we have chosen a technological marvel already belonged to us. In many cases, customers decide to change already taken the decision after testing the vehicle. Increasingly, test drive is also used by people who really do not plan to buy a new car straight from the living room (we have because in this case the count of the really high costs), but I just want to ride a selected vehicle due to, for example, interest in Automotive whether the nature of the work.
