PROCESS

WEEK 7

Title: Description of the whole process
Objective: To clarify the whole process in making this project
Content:Below is the clear image of this project. Where i found it more efficient in making more output power. This is because i use the alternator instead of the build in magnets and solenoids.

Sketching of the overall project

As can see here, there have a pedal, pulley and belt, alternator, spring and last but not least a battery. The pedal act as an input mechanism. There have two inputs which is from the left and the right. People may step at both directions in order to get the output power. Below the pedal, we can see is the spring, which is it's helping the pedal to go back into its position. While the pulley and belt is function as the catalyst of energy reaction brought by the pedal toward the shaft of the alternator . Alternator will then rotates which gives a power to it. This power will convert into electrical power.

Analysis:

Based on the process above, it showed that the alternator will convert the mechanical energy to electrical energy in the form of alternating current. Let's refresh about the principle operation of the alternator..

" Alternators generate electricity using the same principle as DC generators, namely, when the magnetic field around a conductor changes, a current is induced in the conductor. Typically, a rotating magnet, called the rotor turns within a stationary set of conductors wound in coils on an iron core, called the stator. The field cuts across the conductors, generating an induced EMF (electromotive force), as the mechanical input causes the rotor to turn."                                http://en.wikipedia.org/wiki/Alternator
