Use of mechanical force to generate electricity
Summary
The need for energy is a confirmation from the beginning of life itself. An organism to grow and reproduce requires energy, the movement of any animal involves an energy expenditure, and even the very fact of the respiration of plants and animals implies an energy action. In everything related to individual or social life, energy is present.
Obtaining light and heat is linked to the production and consumption of energy. Both terms are essential for the survival of the earth and consequently of plant, animal and human life.
The human being from his first steps on earth, and throughout history, has been a seeker of ways to generate that necessary energy and facilitator of a more pleasant life. Thanks to the use and knowledge of the forms of energy, he has been able to cover basic needs: light, heat, movement, strength, and reach higher levels of comfort to have a more comfortable and healthy life.
Abstract
The need for energy is a realization from the very beginning of life itself. An organism to grow and reproduce requires energy, the movement of any animal is an energy expenditure, and even the fact of the breathing of plants and animals implies an energetic action. In everything related to individual or social life energy is present.
Obtaining light and heat is linked to the production and consumption of energy. Both terms are essential for the survival of the earth and consequently of plant, animal and human life.
The human being from his first steps on earth, and throughout history, has been a searcher for ways to generate that necessary energy and facilitator of a more pleasant life. Thanks to the use and knowledge of the forms of energy has been able to cover basic needs: light, heat, movement, strength, and reach higher levels of comfort to have a more comfortable and healthy life.
THEORETICAL FRAMEWORK
Concept of energy: Energy is the ability to produce some type of work or put something in motion.
Different forms of energy:
The mechanical energy is used to move to another body. This in turn is divided into two energies: potential energy (it is the one that bodies have due to the position in which they are, that is, a body in height has more potential energy than a body on the ground surface) and kinetic energy (is what bodies have due to their speed).
The hydraulic potential energy is obtained from water falling from a height at a lower level which causes the movement of hydraulic or turbine wheels.
Caloric or thermal energy : it is the one that is transmitted between two bodies that are at different temperatures. One of the purposes for which heat energy is used is to cause movement of various machines.
The chemical energy is generated by the food and fuel, or more precisely, the contained chemical molecules and which develops in a chemical reaction. We know the result of food in our body: we develop energy to do different jobs. Energy from burning coal, wood, oil, and gas powers engines and provides heating.
The radiant energy or light is one that most often see as light and we can see things around us.
Electrical energy (or electricity) : is that produced by the movement of electrons through a conductor. It is divided in turn into magnetic energy (energy from magnets), static and electric current.
The nuclear or atomic energy is coming from the core of the atom, the most powerful known so far.
Wind energy is that obtained through the wind, thanks to the kinetic energy generated by the draft effect. Wind energy is characterized by being an abundant, renewable and clean energy.
The solar energy is obtained from the use of electromagnetic radiation from the sun, solar radiation reaching the planet can also be exploited by means of sensors that using different technologies (photovoltaic cells, heliostats, thermal collectors) can be transformed into thermal energy or electricity and is also one of those classified as clean or renewable energy.
The geothermal energy corresponds to the energy that can be obtained based on the use of the internal heat of the earth
Tidal energy : It is the result of the use of the tides, it is due to the difference in the average height of the seas according to the relative position of the Earth and the Moon and that as a result gives the gravitational attraction of the latter and the sun on the oceans .
Energy transformations
1- Chemical energy is transformed into electrical energy using a battery. During this process, when the battery is heated, we say that there are heat losses.
2- Chemical energy is transformed into thermal energy through combustion boilers, even when we burn firewood.
3- Electric energy can be transformed into mechanical energy by heating the motor, in this case heat losses also occur.
4- Electric energy is transformed into heat , an everyday example is heat plates or heat pumps.
5- Mechanical energy to electrical energy .
6- From hydraulic and wind energy we obtain mechanical energy .
7- Thanks to solar energy we obtain electrical energy .
8 - Nuclear energy is transformed in nuclear power plants into thermal energy .
9- The hydraulic energy of a river changes to mechanical energy , through mechanisms that activate stone mills to grind grain.
10 - The potential energy contained in a soda bottle (gas and compressed liquid) is released, transforming into kinetic energy that drips the liquid with force.
11- The thermal energy of fossil fuels is transformed into kinetic energy through its combustion in an engine to move a vehicle.
12- Tidal energy (use of the tides), is converted into electrical energy through dynamos.
13- Kinetic energy to potential
13.- Potential to kinetic energy
How is electrical energy generated through mechanical energy?
Sustainable energy is that which, unlike traditional energy (expensive, polluting and at some point exhaustible), can be obtained from "renewable" sources such as the sun, air or rainwater. There are other methods of generating energy, such as: a pulley.
A pulley is a simple machine , a mechanical traction device, used to transmit a force , to move or lift heavy things. It consists of a suspended wheel, which rotates around an axis, with a channel or throat on its edge through which a rope or chain is passed.
The belt pulley is very useful for coupling electric motors to other machines (compressors, drills, fans, electric generators, saws ...) since it allows a rotary movement to be transferred from one axis to another. With this type of pulleys mechanisms such as the speed multiplier , the gearbox and the pulley train are built .
In my case, I used it to connect it to an electric motor, transmitting force and generating energy.
Physical law that allows converting mechanical energy into electrical energy:
Energy Conservation Law: "Energy cannot be created or destroyed, it can only be changed from one form to another, but the total amount of energy never changes."
TARGET
Demonstrate the production of electrical energy making use of the knowledge acquired in the field of mechanics, put into practice the construction of a pulley that connected to an electric motor and using force can light two LED bulbs, this with the intention of demonstrate energy transformations and know the alternatives that can be put into practice to satisfy human needs without negatively impacting the environment.
MATERIALS
Quantity Description
1 Electric motor
two Color LED spotlight
1 Cable
two CD
1 Cardboard circle. Radius cm
1 Band
1 2 inch screw
1 2 inch galvanized nail
3 Nuts
4 Washers
1 Clamp
1 Wood base
1 Silicone stick
1 Silicone gun
Insulating tape
PROJECT DEVELOPMENT
Get two CDs and cut a cardboard circle 5mm smaller than its circumference, then stick one side of the cardboard to a CD and do the same with the back (use a lot of hot silicone so that it does not come off).In the center of the cardboard circle, make a hole the size of a 2-inch screw and with the same screw check that the disc turns without complications.
With the help of a drill make a hole in the wooden base; In this hole insert a 2-inch screw with a nut already in place, and when it is inside, place another nut but on the opposite side, after which insert a washer so that it is well fixed.
Make a hole in the plastic plate of the CDs to be able to place a nail, you will again need help from the drill.
Then put the center of the Disc in the screw that was already attached to the wooden base, reinforce it with another screw and a washer, this will give it support and will not allow it to move improperly.
To connect the motor: it is necessary to leave the cables without plastic only in the part of the tips, making the wire free.
Tie each wire to the motor connectors
Attach the LED bulbs to the cables but on the opposite side.
Hold the motor 5 cm from the CD on the base
As a next step, place the elastic band between the CDs so that it is in the space of the cardboard and next step, join it with the motor
Begin to turn the pulley so that the LEDs light up.
ANALYSIS AND CONCLUSIONS
The generator that I propose here can also be used for other purposes, apart from turning on an LED spotlight. For example; a clock, a small radio, etc. can be operated.
This experiment generates clean energy since it uses force, that is, mechanical energy to generate electrical energy.
Depending on the speed with which you rotate the system, you will obtain a certain current and voltage, the faster it rotates, the higher the voltage.
If we rotate the electric motor in one direction to the current it generates, it will have a polarity (positive pole and negative pole, always). Whereas if the sense is reversed, said polarity will be reversed as well.
Any electric motor that has permanent magnets can produce electricity in the same way that a common generator produces energy, turning one of these motors causes the internal coils to rotate beyond the magnets, this induces an electric current.
