Regenerative Braking

If you drive in an urban area, you probably realize youre continually stopping and starting on the road. Its a big waste of time, but you might not also realize that its a huge waste of energy. Making a car move forward requires needs a large input of power, and every time you step on the brakes, all the energy you built up dissipates. According to the rules of physics, energy cannot be destroyed. That means when your car slows down, the kinetic energy that was moving it forward has to go somewhere -- its lost in the brake pads and released as heat.  But what if you could store up this energy and use it when you next begin to accelerate? Thats the basic principle behind regenerative brakes, which are widely used in electric cars and trains. Definition Regenerative braking is a system in which the electric motor that normally drives a hybrid or pure electric vehicle is essentially operated in reverse (electrically) during braking or coasting. Instead of consuming energy to propel a vehicle, the motor acts as a generator that charges the onboard batteries with electrical energy that would normally be lost as heat through traditional mechanical friction brakes. As the motor â€Å"acts in reverse,† it generates electricity. The accompanying friction (electrical resistance) assists the normal brake pads in overcoming inertia and helps slow the vehicle. Traditional vs. Regenerative In a tr ­aditional braking system, brake pads create friction with the brake rotors which stop or slow the car. Friction is also produced between the wheels and the roads surface. Both create heat from the cars kinetic energy. However, with regenerative brakes, the system that drives the vehicle does most of the braking. When you depress the brake pedal on a hybrid or electric car, these brakes shift the automobiles electric motor into reverse which makes it run backward, in turn slowing the cars wheels. While running backward, the motor also acts as an electric generator by creating electricity thats delivered into the cars batteries. Best Situations Regenerative brakes are more effective at certain speeds. They are actually most useful in stop-and-go situations. Hybrids and electric cars also do have friction brakes that act as a type of back-up system in scenarios where regenerative braking cant supply enough power to stop. In these cases, drivers should aware that the brake pedal could respond differently to pressure. It will sometimes depress farther towards the floor than usual -- a feeling that can momentarily cause drivers to panic. Hydraulic Regenerative Braking Ford Motor Company and the Eaton Corporation have developed a newer type of regenerative braking system called Hydraulic Power Assist or HPA. When the driver depresses the brake with HPA, the cars kinetic energy powers a reversible pump which directs hydraulic fluid from a low-pressure accumulator (a type of storage tank) and into a high-pressure accumulator. Estimates for HPA indicate it could store 80 percent of the movements lost by deceleration and use it to move the car forward.

Examples Of Revenge Tragedy In Hamlet - 1033 Words

A lot of Shakespeare’s plays allude to revenge and revenge tragedy. Revenge tragedy is seeking revenge for wrongdoings done against someone in a literary work. Usually, the person seeking this revenge is the protagonist and the plot is usually developed throughout their journey to get their rightful revenge. Revenge tragedy is also the central conflict within a literary work. In the play, Hamlet,Young Fortinbras, and Laertes are all examples of revenge tragedy. Hamlet ironically isn’t a person that shows to have the desire of seeking revenge and this is ironic because most of the time the protagonist of a revenge tragedy work desires revenge. Revenge tragedy often sees â€Å"that the revengers pursuit of retribution for past wrongs†¦show more content†¦Ã¢â‚¬Å"Hamlet refrained from killing his own mother, thereby demonstrating Shakespeares greater respect for the rules of manner proper to Persons.† (Grazia 2003) This philosophical criticism used provides an understanding to the meaning of the work because it clearly displays the stance Shakespeare had when it came to philosophy and morals and this could be seen throughout Hamlet as well. Shakespeare is more able to get his meaning and message of his literary work Hamlet over to the readers by describing their psyche and their subconscious thoughts, as seen with Hamlet several times. Psychoanalytic criticism is the idea that literary text express the private unconscious desires of the author as well as their inner psyche or persona. Shakespeare constructs Hamlet to be a very psychoanalytic character. The literary text of Hamlet’s thoughts tie to his desires and grievances. In the work, Hamlet tells his father that he will fulfill his father’s wishes and get revenge on Claudius, his uncle. This brings upon the idea of Paternity(his father’s wishes) against law as well as religion. The destress that Shakespeare painted Hamlet to be in(or the literary text) may des cribe why there was so much friction between Hamlet following up on his father’s wishes.

Humanisitic Perspective Free Essays

The Humanistic Perspective The humanistic perspective in psychology says that we are responsible for our actions when it comes to violence. I believe that the humanistic perspective is the best way to describe the actions of violence. There are many examples of this that have been studied that support this perspective. We will write a custom essay sample on Humanisitic Perspective or any similar topic only for you Order Now Some examples of violence that support this perspective include Joel Rifkin, the two kids thrill kill. Humanistic psychology is the constructive view of human self-determination. It is the interpretation of the behavior of someone is intentional. This means someone’s actions with violence are their choice and they are conscious of what they are doing. The humanistic perspective believes the person who is acting violence is responsible for their actions. Violence in my opinion can be best explained in the humanistic theory. People know what they are doing and it is their choice if they want to do it. When it comes to violence people are capable of knowing what is right and what is wrong. In the case of Joel Rifkin, he was a serial killer who murdered prostitutes in the early 1990’s in New York City. He was fully aware of what he was doing and his actions were intended. In an interview after he was convicted Rifkin told investigators the reasoning behind why he continued to kill. He said that there was a thrill to killing and it gave him a rush of adrenaline. This is an exact example of the humanistic perspective because he realized what he was doing and the consequences that may come along with his actions and he continued with his violence outbursts. A thrill killing is premeditated murder committed by a person who is not necessarily suffering from mental instability, and does not have anything against them, but is instead motivated by the sheer excitement of the act. In the case where the two young boys acted out and killed one of their classmates for the â€Å"thrill† of it is a perfect example of the humanistic theory. Although they were young they knew that killing someone for fun was wrong and they did it anyways. Their behavior was intentional and pre-determined. These terrible crimes are great examples of the humanistic idea and why it is the most important perspective when studying violence. How to cite Humanisitic Perspective, Papers
