The Physics Of A Wind Tunnel

The Divine Wind, written by Garry Disher, is a novel in which not only shows and describes the struggle of characters during World War II in Broome, Australia, but also the many aspects of prejudice which affect namingly Ida Penrose, Mitsy Sennosuke, and Magistrate Killian.

The Boy Who Harnessed The Wind tells the incredible true story of William Kamkwamba and his quest to bring electricity to his poor town in Africa. Although many help him throughout his journey, William is the main character and main protagonist of the book. Throughout the novel, he reflects on his adventures leading up to his creation of a windmill that powers parts of the town. In order to accomplish such a feat, William had to be hardworking, mature, and creative. William exhibits all of these qualities and many more to prove that he is the best thing that happened to Malawi during his lifetime.

The novel The Divine Wind (1998) by Garry Disher and the 2003 film, Japanese Story, directed by Sue Brooks both explore the theme of 'love' through the use of novel and film techniques. Through the studying of the context and textual form of both of these texts, a greater understanding of the important ideas is achieved. This includes exploring the context, the characters and the key theme of love.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

A Betz manometer is used to measure the tunnel pressure, which is given in mm0, which can then be used to calculate the wind tunnel speed. This pressure was given as 20.25 mm0. The barometric pressure was recorded to be 761.5 mmHg, which will be converted into Pascals. The ambient air temperature was taken to be 23.5

Aircrafts are and always have been a great mode of transportation and come with many clear advantages over many other forms of transportation . This in turn may be one of the main causes of their popularity and success over the years. Aircrafts are used commercially, Privately and they even have military applications. Aircrafts have always been an iconic sign of freedom. Even in the media and in commercial advertisements an airplane can be a symbolic tool used to instill security, freedom and luxury. Although there have been a great many advancements in mechanics and engineering of the aircrafts over the years, and many people consider them to be a reliable mode of transportation they still all have the capacity for mechanical or structural failures. In this paper we will begin to explore some of the main causes of these failures as well as the mechanical and structural factors behind them. An aircraft will typically fail because of an excess of stress applied to one or multiple mechanical or structural components. A more exact definition of stress is; “The force perpendicular to the cross sectional area of the member divided by the cross sectional area.”(chapter 8 lecture) There are several different types of stress and certain points of stress on an aircraft are more susceptible to damage or failure. In this paper we will also begin to analyze these factors to provide a more clear understanding of the mechanical and structural factors of aviation. According to Dr. Hans

In the story The Boy who Harnessed the Wind, The main character, and author, is a teenage boy by the name of William Kamkwamba. He was able to apply everything that he learned, and learned extremely quickly. He could lead his friends when they needed it, and when they didn’t. These three characteristics; intelligence, creativity, and persistence, are what best represents him.

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

When looking into doing a natural type of observational research we are wanting to understand our fan in its natural habitat, or in the real life environment. This is

The purpose of the lab is to find a projectile’s horizontal velocity and make comparisons of the effects of different inclined planes with the projectile of a ball.

Abstract: A force table that had three weight hangers, numerous masses and pulleys attached to it, which were used to reach static equilibrium. Third angles for each of the systems were: System 1:349.8, 350.3, 350.1; system 2: 8.3, 9.1 8.8; system 3: 9.8, 10.5, 10.2; system 4: 58.3. 57.5, 58.8; system 5: 48.7, 49.1, 48.1.

First, aerodynamics is the study of the motion of the air. Aerodynamics consists of 4 variables, which is thrust, gravity, lift, and drag. (Tennekes,H, 2009) Aerodynamics has to do with almost everything dealing with air of course.(Tennekes,H ,2009) For example, it can be air crafts, it can be wings, it can be birds, it can be a race car. Birds need aerodynamics so they can glide in the air so they can also gain enough speed to catch prey. Like a hawk swooping down 70 miles an hour to get a mouse to eat. Race cars need aerodynamics so that the car structure can have the most air resistance it wont apply as much pressure onto the car. Like birds air crafts also need aerodynamics for the wings on the aircraft or the weight of the aircraft.

There are several aspects involved in the dynamics of airplane and how they become airborne. This report will address the main physics involved and mathematic formulae that prove how airplanes get above the ground from a small fighter jet to a massive Boeing 747. The necessities involved in keeping there massive weights in the air and the extreme forces needed to land these airplanes and bring them to a halt will also be explored.
