Mechanics




As the toy is pulled along by a child, the eccentric cam rotates as it is fixed to the axle and the wheels. The heads and connecting rods move up and down as the axle and eccentric cam revolve.This is how some mechanical toys are made.


Mechanical toys

This is a spining toy made during the 20th century. It is preferbly played by children as it is simple and it has a image on the spinning toy.





This toy train was made by the German maker Marklin, it was an early producer of toy trains. They created three different gauges of trains with matching tracks to run on. These were numbered 1, 2 and 3. This creation saw the standardisation of toy train gauges made by other firms such as Bing and Carette so that they could all produce train sets that could be added to. A fourth gauge was created by Marklin a few years after this. This was a smaller gauge and was numbered 0.

Mechanics

Mechanics (Greek Μηχανική) is the branch of physics concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effect of the bodies on their environment.
The discipline has its roots in several ancient civilizations (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, and especially Newton, laid the foundation for what is now known as classical mechanics.
