History of Planes essays

History of Planes essays Have you ever wondered who was the first person to make a flying machine? It was not the Wright brother. If you want to know just keep reading more about the history of the planes and how it evolved. Whenever I see a plane the first question that comes to mind is "What is causing that thing to stay off of the ground?" Well I finally discovered the answer. When a plane flies there are four forces at work that keep the plane flying. These forces are lift, thrust, gravity, and drag. Airplane wings are created with a special design called an airfoil. The airfoil design bulges out more on the top than on the bottom. This causes the air that hits the wing to go off into two different streams, one that goes over the top and one that goes under, and they both meet up in the back. The air moving over the top of the wing is caused to go faster than the slower moving air on the bottom. Faster moving air has less pressure, so this causes the pressure on the bottom of the wing to be greater and the plane is lifted. This effect is known as the Bernoulli Principle. This principle was developed by Daniel Bernoulli who was a Swiss mathematician and physician. He developed the principle in the 18th century. When a plane creates lift it overcomes the force of gravity that is pulling the plane down. Air pressure plays a big part in flight also. When you think about flight you have to realize that air pressure is a force pushing on every square inch of an airplane. When a plane is parked the air pressure is distributed evenly around the plane's surface. When a plane is in flight the pressure on top of the wings pushes down less and the pressure on the bottom of the wings pushes more. This is what causes the plane to feel a lift. Another force that has a great part in flight is drag. Drag is the force pulling the plane backwards. Drag is created when the air collides with the airplanes wings and creates fricti...

New Music essays

New Music essays The music industry ripping off the kids! There was a time when music had integrity. Back when the gangsters and racketeers ruled the music business, the music had a real sense of integrity to it. That was back when gangsters knew of "this hot new band/artist" they had noticed in their buddy's club. Then, if they owned their own club, they book that band for gigs. Or maybe a relative of theirs was in a band, and that band had street credibility; all they needed was a break. The bands took pride in making a full album, a collection of songs reflecting their current state of affairs. Back then the people who ran the record companies were music fans. In the last ten years, however, a disturbing trend has taken over. While all of the rockers were out entertaining the people, all of the scholars were off getting their business degrees. This led to a massive take-over. When the scholars finished their schooling, some of them used their business degrees to get into the music business. They became record label executives, and as a result, they viewed the record label as more of a bank then an entertainment industry. Of course, every label gets in the game to make money, but the simple fact is that music fans will buy whatever they are told to buy, for the most part. Gone are the days of bands having to prove themselves on the club scene, building their live performance and song repertoire. The music business is now a fast-food industry - 15 minutes of flash, here today gone tomorrow artists. The ones who suffer are the kids, but the target demographic that the labels go after are none the wiser. An at-home, online, record store that allows the fans to pick and choose their music. Technology has taken the music world by the throat, and there's no better tool to promote music than the Internet. An online record store would put the power in the people's hands, instead of putting the people into handcuffs. The first thing you would ...

The Buzz about Burt's Bees - Essay Example wasteful packaging, using the best ingredients, and refusing to engage in retail business through chain stores that regularly violate environmental principles. It is this commitment to ideals that has set Burt’s apart from other manufacturers. 3. Soap is soap, but some is better than others – for a price. Burt’s Bees faces limited competition from more traditional personal-care products of larger companies from Procter & Gamble because of the specialty of their personal hygiene and beauty products. The larger companies cater to a much larger scale of manufacture and distribution. As such, they cannot focus on naturally raw concoctions and environmental friendly distribution. It would mean a complete rescaling to attempt to compete with Burt’s. Nevertheless, cost is a factor to most consumers, and it is simply more cost effective to purchase the products of larger companies. In the end, the competition is limited as a balance of supply with
