Hong Kong is well known for its development throughout the city. However it’s a really small city where buildings and homes have to be built taller and smaller, in a size where 7.155 millions of people has to fit in. Therefore the construction process requires a specialist machine. Tower crane is the machine that saved lots of homeless people. This machine is used worldwide. It helps to construct anything that is tall or heavy, the height reaches hundred feet tall and could reach far. Not only it’s the life saving machine to build apartments, lift steels and concrete but it’s also a machine that has physics behind it.
Tower crane is constructed rather difficultly. It has lots of function that made it so unique. Firstly “counterweight” is the main function that relates to physics in terms of lever. It weights approximately 20 tons. The diagram above shows that there is a function called the “jib” which refers to crane’s arm. Both are separated by the “mast. These three function are like a lever. If you look at it in a different approach, the counterweight is the lever’s load, the jib is the lever’s force and the mast is the lever’s pivot point. When a force is applied onto the jib it would go downwards, however the counterweight balances it by using levers’ law. The tower crane can stretch up to 230 feet into the air, which is 70 meters. It can carry anything that weight less than 39,690 pounds. But if the load is applied right at the edge of the jib the tower crane won’t be able to balance the load. It could eventually break or fall apart. There are two lint switches that make sure the operator doesn’t make the tower crane tip over. There are four huge anchor bolts that is holding the base of the tower crane. It’s attached dee...

...ous to use tower crane for construction mens because if they are not following exactly according to the safety rules when climbing up the ladders toward the operating centre, likely you could fall off the tower crane. Ultimately for people within reach, if unfortunate a storm come hits the place and people weren’t prepared from this situation or wasn’t informed then the tower crane may loose balance. It could fall if the anchor bold are not stable enough to handle the storm.
Overall I think that tower crane is beneficial. Mostly because it helped Hong Kong to solve the reducing of areas and at the same time to provide citizens more homes. However another problem is they are complaining that the homes provided are too expensive and the area provided for an individual house is too small. Despite that it is a very intelligent invention which based on levers’ law.
After observing Gothic cathedral, you begin to notice the tall walls of stone and stained glass windows. Construction a building of this nature took a lot of architectural design, time, and hundreds of workers. Back in the 12th century, they did not have the modern technology that we have to build cathedrals in less time. In France, they have created a prototype to determine techniques used by worker to build of such a building of architectural design. In their findings, they discover that builders used a Roman war engine hoisting machine or “squirrel cage”, to assist workers with lifting six times their own weight. This method was very difficult as one worker described in an interview, because the “squirrel cage,” often slowed down due to the heaviness of the stones. In order to keep the wheel spinning, the workers had to speed up to ensure that the stones would not fall out in mid-air and cause harm to other working on another s...
Every so often workers have to go up the tower and unwind the wire that is located in the generator at the top of the tower (Campbell). The reason they have to unwind the wire is so the wind turbine can turn into the wind to create energy. These wind turbines only rotate one way, they don’t rotate both ways, so after a while the wire turning the wind turbine tightens and the wind turbine is unable to turn anymore. So the workers have to go up to the generator of the wind turbine and unwind the wire manually (Campbell). Also, with all the wiring and gears up in the generator, workers have to go up the ladder which is found on the inside of a turbine, and check to make sure everything is alright (Gipe).
Healthcare for the Homeless (HCH) started in 1985 and was one of the first 19 Federal Funded projects. In the early 80’s, they recognized that homelessness was an issue. In 1987, it was operated out of bonds in Liberty Heights. In 1989, they moved to Park Ave and stayed there for 20 years. In 2010, they moved to Fallsway and still are there till this day and are expanding their building. HCH provides tons of services for the homeless population such as physical health care services, behavioral health care services, and supportive services such as finding housing, keeping housing, finding jobs and much more. HCH wants to decrease the homeless population statistics and provide second chances for everyone individual.
There are many components that contribute to the homelessness in America. Neoliberalism and capitalism are very important contributors to discuss. Under these practices lies multiple factors that not only perpetuate, but also maintain homelessness. In a neoliberal era, there’s a shift of deregulating and privatizing public spheres/programs and move it under the authority of private and individual entities. This includes the lack of support and funding in access to affordable housing, employment, income, public health, and other public assistance. Neoliberalism, poverty, and capitalism has play a key role in sustaining the unequal distribution of wealth and resources among people, which has resulted folks in losing their sense of self.
Homelessness is not something that I could ever imagine completely. I, like everyone else, have a simple idea of what it would be like to be homeless. There is so much more to being homeless than most believe. My exposure to Habitat for Humanity is showing me some about the idea of living in a lower income family. This exposure is an experience that all high school and college students should have.

There are currently over 200 million people living on this earth with no place to call their home. England contains a very small percentage of this population, around .002%, while its capital, London, holds an even smaller amount. This small amount is not surprising, because the United Kingdom has a very encompassing Safety Net. This Safety Net is in place to help those who are or are about to become homeless. In fact the United Kingdom’s Safety Net is one of the most comprehensive in the world (“Homelessness Facts and Figures”). Unfortunately many people still end up homeless, over 6,000 in the city of London. Many, more fortunate people, strive to help those sleeping on the streets, whether on their own or through a charity like St. Mungo’s on Broadway. On the opposite end of the spectrum, there is an unfortunate amount of people who are not only apathetic, but cruel to the people left in a tough situation. These people, and all other people, are homeless too, searching to find a home in heaven. Humans are not
In the competition known as Science Olympiad, there is an event called “Boomilevers.” This event is comprised of building a structure to be attached on one side to a wall and bear the maximum weight possible on the other side, while the structure itself weighs as little as possible. The Boomilever is a long standing Olympiad Event and requires acute attention to detail and a critical mind in architecture in order to achieve the maximum efficiency score possible. There are many limitations and guidelines set forth in the Olympiad rules, defining how tall and long the boomilever must be and how the boomilever must attach to the wall. This leads to construction much like a real life situation, where resources must be utilized efficiently.
Next, The Eiffel Tower is a renowned monument for France. Being that it was originally built as an entrance way, some precautions were made. The safety token was moveable staging, guard rails and screens only one man died during construction. (Eiffel Tower). The tower stands 320 meters tall it uses over 18,000 pieces in the steel structure. Each year the high heats cause the structure to grow six inches, but then retracts back after the summer time. So, that is why the idea of thermal rivets were used in assembly, because the rivets allow the structure to keep its shape. Over 2.5 million rivets were used. (Eiffel ...

One World Trade Center (WTC) is the tallest building in the Western Hemisphere measuring up at 1776 feet tall. The built output sets new standards of design, construction, and prestige. Its beauty in New York City’s magical skyline makes it an icon. It is the most recognised and desirable office address in the world. In this essay I plan to argue that the social, political and economic status of society has affected the built output of this building considerably, for the good. Making the building one of the best skyscrapers in the world.
The tower of Pisa is a well known masterpiece of architecture and it is considered the crowning glory of Pizza. It is the tallest building structure in the whole of Europe and a real example of the medieval engineering . The tower of Pisa is also known as the bell tower and it is a part of a big complex that includes four important buildings. The tower was built by Guglielmo and the sculptor Bonanno and the tower was made of some storeys and its final point is the bell. The purpose behind building the tower was to use it for gravity experiments. In addition , people of the city wished to display how wealthy and prosperous they were. The construction of the tower began in 1172 and it was constructed in the city of Pisa. It took 234 years to build this tower as it was built in three stages. It is known as the leaning tower of Pisa because of the leaning of its foundation and every year the leaning of the tower increases for some inches. The exact cost of constructing the tower is not known because the tower was built over some stages. However, it is estimated to be very high.

The tower served the city and the rest of the world through scientific research, which ensured the tower would not be torn down.1
The Leaning Tower of Pisa, also known as the Torre Pendente di Pisa, known for its renowned work of art is located in Pisa, Italy. The mastermind behind this historically significant masterpiece is the famous architect, Bonanno Pisano. The tower is in the shape of a circle, which was first constructed on August 9th, 1173, measuring about 185 feet (56 meters). Originally, the tower was designed to have eight stories; however, within the year of 1773, many problems occurred, causing only three of the eight stories to be completed. Due to a war which occurred, the building was incomplete. The war broke out among the Italian city-states, and construction was halted for almost a century (www.brittanica.com). This pause allowed the tower’s foundation to settle and likely prevented its early collapse (www.brittanica.com). Because of the pause, the rest of the stories were completed during 1319. There were two pauses between the constructions of the Leaning Tower of Pisa, first for 100 years, and the other occurred in 1284. Both of the pauses took place because of wars. The tower began to lean on one side due to the soft ground underneath the building; problems arose when the weight of the tower couldn’t be supported by the ground. In modern time, the famous masterpiece would’ve been 840 years old (www.softschools.com). The tower is a freestanding bell, famous for the settling of its foundation, causing it to lean 5.5 degrees to one side. However, over time, many operations were done, trying to straighten the tower, yet it only straightened out by less than 4.0 degrees. However, the lean became worse as construction continued for several decades. Gratefully, the lean was stabilized and partially fixed between 199...
