Mechanisms

We can find different types of mechanisms in many devices, for example this bicycle, a rod, a seesaw, a clock...

However, could you explain how a mechanism works?

If you watch the following presentation about mechanisms  on Prezi, you will be able to think their meaning over, and learn different types of mechanisms.;-)

Task

• Watch the previous presentation, and copy the information in your notebook.
• Draw three presentation mechanisms, and write two examples of objects that have these mechanisms. 
• Are you ready to answer this question yet? Could you say how these mechanisms are called?
