1. Linear motion mechanisms
Rotary motion mechanisms
Mechanisms that transform motion

2. We´re surrounded by objects that move or
have the capacity to move.
 The system of gears with a chain for bicycles. The cogwheels of a clock.
The lever of a seesaw. The pulley used to get water from a well.
 All of these examples make our lives more confortable and pleasant.

3. Mechanisms are devices that transmit and
convert forces and motions from a driving
force (input) to an output element.
They enable us to carry out certain tasks
with graeter comfort and less effort.
