This “Mythbusters” episode begins by stating the first myth the team will pursue. It is said to be extraordinarily controversial. You are able to find thousands of pages on the World Wide Web and their personal Mythbusters Discovery fan page. The myth is: If a plane was placed on a conveyor belt, both going the same speed in opposite directions, will the plane be able to takeoff? Majority believe that the plane will stay stationary, but this myth was never tested until the “Mythbusters” crew decided to end the myth once and for all. Normally a plane sits on a runway, spins up its engines and moves forward, gets enough wind under it's wings, and takeoff. In this experiment the plane will not be on a runway, but a conveyor belt and that's matching the speed of the plane going forward in reverse. …show more content…
While spending the day trying to perfect flying a remote controlled plane, Adam had a harder time. Adam has an exuberant personality. He is not likely to crash as soon as possible. Jamie, on the other hand, is a very controlled person. He has a controlled personality and is likely to fly a very controlled pattern. Once they gained all they experience and practice they needed from flying a remote plane, they began to set up their experiment. They used the plane from the practice flies and Jamie’s old treadmill to begin with. First, they had to find the play plane takeoff speed. The plane’s takeoff speed was 11.3 mph. Next the treadmill (conveyor belt) had to matched to that very
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
The episode Mypods and Boomsticks from the noteworthy satirical TV show The Simpsons is an effective piece of work designed to criticise Apple products and customers and condemn racism towards religions. This episode revolves heavily around Bart and how he deals with racism towards his new friend, Lisa and the problems of being a consumer of Apple products and Homer with his racism towards a religion he doesn’t understand.
Major Ted Tolman’s F-105 Thud fighter/bomber streaked through the air at just under the speed of sound. His aircraft performed modestly at best, struggling to maintain its speed and altitude under the heavy load of ordinance and fuel it carried under its wings (Patrick).
The experiment test-bed is composed of a DC motor, an engine, a chain drive, a shaft and other accessorial components. The DC motor is used to drive the engine shaft and its speed can be up to 1450 r/min.
Imagining Reality: The Presentation Of The Theme of Illusion VS Reality in “An Occurrence at Owl Creek Bridge”
Thirdly, the experiment design was prone to human error. Human reaction times make it impossible to record accurate results with a stopwatch. Similarly, the calculated velocity values were an average velocity. Realistically, the instantaneous velocity at the start of the tabletop should have been measured so that the velocity is unaffected by friction, drag and other external
“The Illusionist” is a short story by Steven Millhauser, which was adapted into a movie directed by Neil Burger in 2008 which both take place in Vienna. The short story’s plot revolves around Eisenheim and his relationship between himself and the state, which is still featured in the movie. Eisenheim’s illusions also cause him a bit of trouble; in the short story the cause of trouble is an illusion, which produces two spirits by the name of Rosa, Elis, and a boy who appears to be no older than eight. In the movie adaptation, the final straw that causes the Crown Prince to finally pursue persecution of Eisenheim is the illusion that again, produces a spirit, which turns out to be his dead fiancée. Because of Inspector Uhl’s growing obsession of Eisenheim, throughout the movie and the short story, it further ignites the blur between what is the reality and what is his illusion. Uhl’s obsession over Eisenheim and his illusions helps blur the reality around him.
In Richards Willing’s “CSI effect” the author tells the reader how, as a result of crime scene shows’ popularity, the misconceptions they create, and the combining of real life events with TV fantasy, crime scene shows have affected jurors and the oucomes of court cases. The shows’ popularity has increased peoples’ interest in forensic science and has caused workers and students to transfer into the field. The second effect crime scenes created is the misconception concerning when to use forensic tests, as well as misconceptions about the speed and accuracy of forensic workers and machines in tracking and identifying the culprit. Willing tells of a murder trial in Arizona in which the defendant’s bloody coat was listed as evidence, but was not tested. Although the defendant had already told investigators that he was at the scene of the crime, with the jacket, jurors asked for forensic DNA evidence linking the defendant to the bloody coat and to the crime scene. The juror’s exposure to crime scene shows had given them knowledge of forensic tests, but not knowledge of the proper use of the tests. Crime scene shows mix real life with TV fantasy. According to willing’s studies, highly attractive forensic workers and stunning suspects, along with very neat crime scenes on crime scene shows deemphasize the real life violence and brutality of crime. Similarly, tv reality shows have influenced people’s ideas about real life and real relationships through the effects of image, misleading information, and popularity.
Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)
For centuries, human beings have unknowingly used the very physics principles seen in the roller coasters of today in pursuit of not only thrills, but also survival. As early as 30000 years ago, our ancestors were using some of the most basic laws of physics seen in roller coasters today to their advantage. Although they didn’t quite understand why, when they threw a wooden spear high into the air at a woolly mammoth the spear would fall to the ground accelerating at every second. Of course, they were demonstrating gravitation. Physicists of the 16th century knew how to harness the law of gravity as well, using it to construct the first roller coaster- consisting of simple ice slides accelerating down 70-feet slopes before crashing into giant piles of sand (the latter part demonstrating another important physics principle: inertia.) As the centuries prog...
Recorded videos were used to analyze the movement patterns of the runners. The participants were an elite (male) and a novice runner (female). The elite runner used a standard track field while the novice used a treadmill in a standard gym. The result showed that the elite runner had a longer stride than the non-expert due to his long legs. The novice runner required less force to move her body than the elite runner. The expert had longer stride resulting in longer step length which made him move faster than the novice. As the feet of both participants touched the ground the expert had a higher ground reaction force than the non-expert. The elite had a higher cadence than the non-elite because his legs moved faster. During stance phase, they both have one foot on the ground and as their foot first hit the ground they both slow down. However, the novice was slower because the elite had a faster speed making him spend less time in the
The Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter.
