Mechanisms
In this unit we are going to study the fundamental characteristics of those machines and mechanisms that facilitate people the work, saving them physical efforts and increasing this way their output. The above mentioned mechanisms are going to take part in the future of many of the technological projects that are going to be constructed in the classroom, that is the reason why they need to know and understand their working.
