Wind tunnel

two minutes in the the tunnel to freedom when she had strongly considered turning back. Each stop brought her closer to otherworldly wailing that got louder with each step. Pausing, she tapped Darla’s shoulder. “That is the wind?” “Yes. There is a strong wind that blows through the chasm, and the many crevices and small caves that dot the path down create the sounds.” Darla squeezed Maela’s arm. “You will see.” Maela nodded and followed as Darla continued forward. The tunnel they were in was small

waste to all that resided on the surface of the earth, and the wind, oh, the wind, it tore a path through the air with such vehemence that the very foundation of the asylum seemed to quiver under the strain like a human bone preparing to splinter. Through this, I had been quietly dining upon the daily rations of stale bread which serve as my only sustenance while a resident of this wretched habitation when a particularly violent gust of wind tore the last remaining chunk of the bread from my grasp. The

Sometimes the wind would not be perpendicular, in which the oscillation of the bridge was less, but there was still some oscillation. On November 7th, 1940, the Tacoma Bridge collapsed because the oscillation of the bridge became extreme. The oscillation of the bridge was caused by a wind speed of 42 mph (HistoryLink.org). After, approximately, an hour of a corkscrew like motion, the bridge collapsed

allowed wind to pass through but plate girders, on the other hand, present an obstacle to the wind. As a result of its design, it was proved that the bridge was too light and unstable. And causing alloping Gertieaction which were driven by the wind were being experienced by the bridge. During the morning of 7 November 1940, the wind with around 56.3 km/h (35 miles/h) excited bridge`s transverse vibration mode to its maximum amplitude of vibration of 0.5 m within three hours. Then the wind started

behaviour. First the paper will discuss normal wind selectivity of migratory flight in birds as described by Akesson and Hedenstrom (2000), then will go on to discuss basic air circulation characteristics in mountain environments and how the Bar-headed Goose has adapted to its iconic migration over the tallest mountain range on Earth: the Himalayas. The research draws from a satellite tracking experiment conducted in Sweden that explains normal wind selectivity in

Everyone knows and loves the classic tale of The Wind in the Willows, the story of how three friends, Rat, Mole, and Badger have adventures wherever they go, whatever they decide to do. So what is the appeal in their homes? The essence of homes is the happiness and memories made in it, and homes are the center of life, where one can see the riches, joys, and pleasures found in each of their little residences. In the book, Rat is an easygoing fellow with a kind heart. He is contented with

The Tacoma Narrows Bridge was designed for a wind speed of 100 miles per hour and a static wind pressure of 30 pounds-force per square foot but unfortunately the bridge failed at a wind speed of less than half and a static wind pressure of one-sixth (Delatte, 2009). This phenomenon raises a big question mark on how this is possible. At first, resonance was suspected to be the main cause of the bridge failure (The New York Times, 1940). After some proper research and thorough investigations by engineers

The objective of this lab was to observe how surface conditions affected Temperature, moisture, and wind. II. Methods: The materials that were used to complete this lab was an instruction packet, probe thermometer, IR gun, the Kestrel weather instrument, and a finger. III. Results: For this lab my classmates and I all had to go to different locations to collect the data that was needed. Some of us were out in the sun, others were in the shade so we all got different answers on our sheet. For my

The hill, a wind tunnel during a thunderstorm, seduced me with its lush green grass, but I did not so easily forsake the prospected security of the shelter. The shelter, an old, weathered, abandoned barn squatted regally in the meadow, as if ruling over the valley below it. As dusk deepened into night, I carried my sore but happy body inside where I cooked a wondrous meal of pasta then swiftly passed into unconscious bliss. As I learned when I awoke during the night to the roaring wind outside,

everything in its path, and leaving many people homeless. Hurricanes are often measured on a scale of categories 1 to 5, with a category 1 having winds of around 80 km/h, and a category 5 having winds of over 250 km/h. Hurricane Sandy was only a category 2 hurricane, but it’s massive size gave it momentum, and allowed it to travel a longer distance. The winds went over 130 kilometers per hour, and water levels flooded over 9 feet. The hurricane hit hard up north, where it devastated cities with flooding
