Buoyancy Lab Report Essays

Buoyancy Lab Report Essays Buoyancy Lab Report Paper Buoyancy Lab Report Paper From information learned in the accompanying Fluid Mechanics lecture course, basic formulas can be applied to solve for the specific weight of the object in question. The experiment performed will involve the buoyancy principle and include calculating the volume displaced of a submerged object. This is laboratory experiment under a controlled environment. The results of this experiment can be found by using the weight of each object when dry as well as submerged in water in order to determine the specific weights of the objects. This concludes the Archimedes principle to be true in that the collected values were very close to those of the available accepted data for the respected materials. These findings will likewise set the basis for fluid mechanics study to come during the remainder of this course. Objective Introduction: The objective of this lab experiment is to gather enough information to be able to use the buoyancy principle to determine specific weight of multiple objects. Submarines apply Archimedes Principle when changing depth. A submarine ivies deeper by opening its ballast tank, collecting enough water to increase the submarines weight to an amount greater than the buoyant force. By pushing water out of the ballast tanks, the submarine becomes lighter than the buoyant force, allowing the submarine to rise. Archimedes Principle is used in everyday industries which involve buoyancy, to include watercraft, weather balloons, and even life-preservers. It is necessary to know whether or not something will float, as intended, or sink below the surface of the fluid in which it is In the year 250 B. C. Greek mathematician Archimedes of Syracuse published On Floating Bodies, a book containing various scientific and mathematical principles which he had scrutinized and eventually proved through rigorous trial and error While never fully verified, the legend of the buoyancy principle was verified by Archimedes himself after noticing the water level rise after stepping into his bathtub one night. His exclamation of Eureka! , Greek for l found it marked this significance and had been used as a verbal mark for discovery in the English language ever since. In modern engineering, Archimedes principle can be seen in nearly every real world application. In the basic sense, calculations for ocean- going vessels are wholly dependent on the buoyancy principle. For a more broad sense, the principle of material composition verification can nearly always come back to soaking and floating an object. And for a more abstract outlook, the floating of blimps, balloons, and lighter-than-air craft is dependent on the fact that their specific weight is equal to their weight displaced divided by their displaced volume. Theory Experimental Methods: Archimedes Principle states that objects in a specific medium (i. E. Air or water) experience an upward force known as buoyant force. In order for something to stay afloat, this force must be equal in magnitude or in the case of lift with a hot-air balloon, greater than, the weight of the volume displaced by that object. Moreover, this amount of substance or in the case of this experiment; the water (or fluid) displaced will be equal to the volume of water displaced divided by the specific weight of the object.

Legitimate authority has the ability to alter these decisions. The fact that authority calls for performance for a certain action is a basis for decision making which is not to be added to all other sound decisions when assessing what is to be done, but should eliminate and replace some of them. The theory is only acceptable if there are limits on what the legitimate authority can fairly order the individuals to do, a reason why it does not essentially replace all relevant decisions. In conclusion, Hobbes and Locke’s approach to decision making can be justified only based on consent. There should be a voluntary formation of political obligation and justice, where justice depends on what the individuals are willing or choose to agree to. Individuals should decide according to the concept of the â€Å"original

Gender Roles in The Thin Man Essay Example for Free

Gender Roles in The Thin Man Essay The period of the 1930s was an offshoot of the â€Å"roaring twenties† or the â€Å"jazz age†, a time when women gained a heightened sense of prominence in the society after the First World War saw young men leaving their homes and their work in response to the nation’s call to arms (Freedman, 1974, p. 374). Towards the end of the war and at the beginning of the 1930s, women became more in control of their liberty, proof of which is their newly recognized right to suffrage (Murphy, 1996, p. 52). They became regular members of the social workforce, thereby giving them a renewed sense of control over their lives. The â€Å"flapper†Ã¢â‚¬â€young women who defied the norms of what a conservative woman is by engaging in casual sex and wearing short skirts, among others—took the center stage, so to speak. As for men, such circumstances only brought them closer to the temptation of pleasing the opposite sex. This is clearly portrayed in the 1934 film The Thin Man. In the film, Nick Charles and his wife Nora represent the life of married couples whose lives are characterized primarily by the attitudes of the social elites—fun meant enjoying martinis and sleuthing. In a way, the couple captures the gender roles of each partner during the 1930s. Nora was a wealthy heiress who had almost everything at her disposal. She was beautiful and seemed to have a passion for adventure owing largely to her living a life of liberty. She was the 1930s woman who saw life as the ultimate provider of adventure in all its daring forms. Nick was a handsome man and a retired private detective who previously investigated and solved murders. He was the 1930s man who was deeply entrenched with his passion for resolving issues no matter what it takes, much to the amusement of the female partner. In fact, Nora was more than delighted upon knowing that Nick accepted the task of investigating the disappearance of his friend Clyde Wynant and the death of Clyde’s former girlfriend, Julia Wolfe. It leaves little room to speculate that Nora was indeed the typical 1930s woman who seized her liberty as if it would never run out, putting her self to risky situations together with her man. She portrayed the woman who embraced the â€Å"flapper† culture with open arms, spending her time drinking alcohol or romantically engaging her partner. While she remained supportive of Nick like a female partner might usually commit herself into, she was on her own a liberal minded individual. For the most part, Nick played the role of the adventurous husband which perfectly complements Nora’s interest in the same. He was someone who lived every danger with such boldness. He was someone who sought the pleasure of his spouse—from accepting her request for him to take the case to completely allowing her to partake in his drinking sessions—no matter what the cost may be. It goes to show that Nick was a man who shared entirely similar interests with his spouse and will gladly fulfill whatever it is that will make his woman happy. It was his role to please his woman. On the other hand, it was the woman’s role to act is if she was herself a man, fully absorbed in exactly the same interests as the husband’s. Here we see the approximate gender roles prevalent during the 1930s. Men and women had more similarities than differences as far as their inclinations are concerned. To a certain degree, there was no â€Å"woman†. Woman drank, dressed and acted in an unconventional so that they may be desired by the opposite sex, and actively participated in fairly dangerous tasks. Her liberty stood at the very core of her character and this made her more appealing to every man. Towards the end of the film, Nick gives in to the implied gesture of Nora to spend the night together in the same bed. The scene is revealing insofar as it gives rise to the idea that women exerted a certain influence or power over men especially when it comes to passionate affairs. The 1930s woman had too much liberty, in fact, that she can do anything she pleases and become pleased in the end. Nevertheless, the 1930s man still had a lot to do with her sources of pleasure.

Difference between Coasean and Pigouvian Solution to an environment problem

Difference between Coasean and Pigouvian Solution to an environment problem Explain in your own words the difference between a Coasean and a Pigouvian solution to an environmental problem? Which type of solution do you prefer, and why? The Explanation of the Difference between Coasean and Pigouvian Solution to an environmental problem. In a very simple way, Pigouvian solution prefer to use government intervention to solve externality while Coasean solution prefer to use market method to solve externality. In detail: Pigouvian theory is based on the method of modern economics especially based on welfare economics; and Pigouvian theory provides a perspective systematic study of the externality problems. According to Pigouvian theory the marginal private net output and marginal social net output has following relationships: Besides the increasing of marginal private benefits, if other people can still get benefit from the private activities, then the marginal social net benefit is greater than the marginal private net benefits; on the other hand, if other peoples benefit is decreasing due to the private activities, then the marginal social net output is less than the marginal private net output. In the first situation the society will get the Marginal social benefit; in the second situation the will face the Marginal social cost. Actually, Externality is caused by the inconsistency between marginal private cost and marginal social cost. .Without externality, the marginal private cost of production or consumption of an item is equal to the cost of itself. When there are negative externalities, there will cost to compensate these externalities. By adding marginal private cost with the marginal external cost we will get the marginal social cost. On the other hand, when there are positive externalities, the benefits which generated by business activities are not fully occupied by the company, but will also become some external social benefits. Through economic model, Pigou shows that because of the presence of external economic effects, the Pareto optimal allocation of social resource can not be achieved by purely individualistic mechanism. Since there is a deviation among the marginal private benefit and marginal social benefit, marginal private cost and marginal social cost; therefore the maximization of social welfare can not be achieved only through free competition. The Government should take appropriate economic policies to reduce this deviation as much as possible. The proper policy is that: when the marginal private cost is less than marginal social cost ( negative externality ), government should impose taxes; when the marginal private benefit is less than marginal social benefits (positive externality) then the government should provide incentives and subsidies. Pigou believes that by using such taxes and subsidies, the externality problem could be internalized. And such policy is known as Pigovian solution, and the tax is called Pigouvian tax. Pigovian solution has been widely used. In the field of infrastructure, the policy is who invest who benefits; in the environmental protection, the policy is who pollute who pay(a.k.a Polluter Pays Principle PPP). Over the years, the problem of how to internalizeof external effects is dominated by Pigouvian theory. To some extent, Coase theory is developed through the criticizing of Pigouvian theory. Coases critique of the Pigovian solution are focused on the following three aspects. First, the externality is very complex; it is not as simple as one side damages the other side. For example, in the case of chemical factory vs. residents, it is unfair to tax the factory without discussing whether the factory has the right to emission or not. Because, it maybe the case that the factory is established years before any resident areas was setup, and in this case, the factory may have the emission rights(The example of factory vs resident is from Ronald CoaseThe problem of Social Cost, Journal of Law and Economics Vol 3:1(1960)). In order to reduce the emission, perhaps the government should encourage residents purchase the redemption instead of just posing tax on the factory. Second, in the case of zero transaction costs, the Pigouvian tax is absolutely unnecessary. Because in this case, through voluntary negotiation of parties, the optimal allocation of resources can be reached. In th is case, with the help of clearly defined property rights, voluntary negotiation can also achieve the optimal level of allocation just as the same effect through the Pigovian solution, then why should the government intervene? Third, even in the case of non-zero transaction costs scenario, we still need to balance the cost of using government and using voluntary negotiation. Pigouvian solution may be an effective institutional arrangements, it also maybe an inefficient institutional arrangements. According to Coase theorem: If the transaction cost is zero, no matter how the initial definition of property rights is, optimal allocation of resources can be achieved through market; if there is non-zero transaction costs situation, then maybe the institutional arrangements and choice is important, however people still need to do a cost-benefit-analysis of about the government intervention. In order to solve the problem of externality, Coasians market solution could just be as useful as Pigovian solution. Coasian solution shows that even there is a market failure it doesnt automatically means we should use government intervention. Which type of solution do you prefer, and why? I dont prefer either one, I think a mix use of both solutions will be more helpful. ThePigovian theory/solution has some limitations. First, the Pigou theory presupposes there is a function of the existence of the so-called social welfare, and the government is the natural representative of public interest, and the government can perceive the public interest and then choose the right policy to reduce the externalities in economic activity through intervention. However, the fact is that public policy itself maybe flawed. Second, the use of Pigovian solution is based on the premise that the government knows the cause of externalities can calculate all marginal costs or benefits, however it is impossible for any government to obtain all information to make a Pareto optimal allocation of resources. In theory, Pigouvian solution is perfect, but the actual implementation maybe largely constrained. Third, government intervention also makes costs. If the cost of Government intervention is more than the losses caused by externalities, then there is no reason for use to use g overnment intervention .Fourth, the Pigovian solution may cause the rent-seeking activities, which will lead to waste of resources and distortions of resource allocation. On the other hand, the Coasian solution is also limited. The fist problem is that in order to make the Coasian solution work, the market should be developed, however, for many developing countries, the whole economy system is still in transforming, I dont think Coasian solution can work very well without a certain protection level toward property right. Second, the costs of voluntary negotiation transaction need to be considered. The feasibility of voluntary consultation is depending on the size of transaction costs. If the transaction costs are higher than the social benefits, then why should we have such negotiation. Third, the voluntary negotiation is based on the premise that property rights are clearly defined. In fact, some property rights of environmental resources such as property rights are often difficult to define or very costly to define. For the environmental pollution problems, policy makers should consider the characteristics of pollution sources, the different costs of regulatory management and institutional arrangement; they should also consider the degree of maturity of the market and many other conditions. Only through a comprehensive consideration can we achieve a better solution.
