UNIT 4 - TRANSMISSION MACHINES

Here is a video of the most visited rollercoaster in the world which is in Australia ,maybe you think that it doesn´t have any relationship with this topic of transmission machines, but it is false because we need pulleys,inclined planes,cranksafts,lots of nuts and bolts..to make it working and of course to have fun in theme parks.THE WORLD IS TECHNOLOGY AND MACHINES that we use day per day lots of times whithout thinking in the service they give to us.
