Effects of wind-loading on bridges Wind Loading Wind is a word that used to describe the motion of the air. It is the natural phenomenon which caused by temperature differential that is resulted from solar radiation. A moving wind that comes in contact with a solid structure will be distracted. Although the wind structure is not fully stopped‚ it still loses some of its velocity. This is due to the frictional force faced by the wind flow and the surface of the bridge. This phenomenon is actually

The Treatment of Black Enslaved Women In the middle of the 19th century‚ thoughts about slavery differed from males to females‚ predominantly throughout the white race. The gender of a slave remained the main controversial issue about slavery‚ due solely on the fact that the treatment of enslaved black women was by far different from enslaved black men.

Slavery in a Woman’s Role Throughout the 19th century‚ women were treated as an inferior species. They were locked into a role in society with no way out. There are three pieces of literature written in the 19th century that describe this large issue very well. A Doll’s House by Henrik Ibsen‚ The Yellow Wallpaper by Charlotte Perkins Gilman and Trifles by Susan Glaspell. In all three of these works a woman was trapped into her role or marriage and each book describes the unique was in which the

Pros and Cons of Wind Power There is no perfect energy source. Each and every one has its own rewards and drawbacks. In this paper I will explore the advantages and disadvantages of wind power. Today the world needs to look at the different natural energy sources available to us. Global warming could be due to our energy craving lifestyle‚ while considering this possibility let’s take a look at some of the pros and cons of wind power. It’s been

The wind farms were created to use for an alternative use to burning coal for electricity. “ It would do so without producing local air pollution or the greenhouse gases that causes global warming” (Layzer‚ 421). The wind farms are a good idea because it is a step to saving the environment instead of burning so much coal. It keeps the air from being polluted and is a step in the direction we need to make to finally make a change with the environment. “Cape wind could offset more than 1 million tons

The notion of slavery‚ as unpleasant as it is‚ must nonetheless be examined to understand the hardships that were caused in the lives of enslaved African-Americans. Without a doubt‚ conditions that the slaves lived under could be easily described as intolerable and inhumane. As painful as the slave’s treatment by the masters was‚ it proved to be more unbearable for the women who were enslaved. Why did the women suffer a grimmer fate as slaves? The answer lies in the readings‚ Harriet Jacob’s

The two types of energy resources I chose were wind energy and biofuel energy. Wind energy uses turbines which convert the kinetic energy in the wind into mechanical power. This power can be used for a generator‚ a generator can convert this mechanical power into electricity to power homes‚ businesses‚ schools‚ and many others. Biofuel energy unlike other renewable energy sources can be converted directly into liquid fuels for our transportation needs usually found from dead plants and animals

The famous memoir of a child soldier and his experiences‚ A Long Way Gone‚ has amassed some controversies on whether the book is all real or if sections of the book are made up. Beah explains that he was a child solider for around 3 years. But new records have been found that it’s only been for around 3 months. Beah describes multiple times about his trauma after being a solider for 3 years which is a pivotal part of the book. The question concerning the validity of Beah’s memoir change the impact

ABSTRACT This document describes the experimental process of developing a non-mechanical hot plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration of the sensors
