Mechanical Clock

The mechanism that I choose is a mechanical clock. It is very useful in our everyday life. Mechanical clocks consist by two parts, a mainspring and a pendulum. The mainspring gives the energy to turn the gears; as a result, the hands move. Τhe pendulum keeps time and ensures that the gears move at the right pace, second by second. Some mechanical clocks have weights that pull the gears at the right pace instead of mainsprings. In conclusion mechanical clock do not need electricity to operate.
