Propeller Governor Operation and Maintenance of Propellers Article

Propeller Governor Operation and Maintenance of Propellers - Article Example With the suspension method, the propeller is hanged by cord and the imbalance noted by the eccentricity between the disks attached firmly and the cylinder that is attached to the part under test (FAA, 2012). However, the suspension method is not used frequently as compared to the knife edge method which is simpler and accurate to carry out. The knife edge method involve the use of two hardened steel pieces that are mounted so that there is free rotation of a propeller (assembled) in between them. The setting of this knife edge test should be done in a room or area free from air motion and other form of hard vibration. Whenever a propeller is balanced statically, it remains in that position as compared to the one that is not statically balanced (FAA, 2012). It should be noted that during the balance check, the blades must be at the same angle. This is necessary because it would enable the person checking to have finite details. The propeller should not rotate to any other position unless specified by the manufacturer, as this will avoid damaging the entire propeller

ESSAY. The Constitutional system in Australia determines how the law is made. Some issues addressed by this are; The Federal government, division of powers, the separation of powers, amending the constitution, the high court and the constitution and transfer of powers. The federal System of government has one central government deal with matters involving the whole nation. This system was adopted in Australia on 1 January 1901.In a federal system of Government there must be a division of powers. Powers are divided between the states and federal government. The powers divided are legislative, executive and judicial powers. These are divided by the Australian constitution. The constitution provides for four types of legislative powers; Specific powers: areas of law making specifically mentioned in the constitution as belonging to the Federal government, Residual powers: powers that the states retained after federation, these are not mentioned in the constitution but became the states powers. Concurrent powers: areas over which the states and commonwealth have legislative power. Exclusive powers: areas over which the federal government has exclusive power.   Ã‚  Ã‚  Ã‚  Ã‚  The Separation of powers means that power is distributed between three arms of government. The three arms are; legislature, executive and judiciary. The judiciary is separated from the legislature and the executive, because of this it is independent and can examine their actions without bias. The legislature is separated from the judiciary and executive powers, because of this it is independent, providing for some rights which cannot be taken away by legislation and this allows provides for regular elections. The executive powers, there is no true separation between these two arm, because the British require that members form the executive arm be chosen from the legislature. However the power of the executive is subject to checks and balances in other ways.   Ã‚  Ã‚  Ã‚  Ã‚  Amending the constitution. Section 128 of the constitution provides the procedure by which the constitution may be changed. The constitution can only be changed if a bill stating the question is passed by both houses of parliament and the change is approved by referendum by the majority of people in a majority of states. It is difficult to amend the constitution because it cannot be amended like any other law; if it were then the federal government could make laws on any area it chose by amending the constitution. For example the 6 November 1999 referendum asked the Australian public ‘do you support an act to alter the constitution to establish the commonwealth of Australia as a republic, with the queen and governor general being replaced by a president appointed by two thirds majority of the members of the commonwealth parliament’.

Before You Buy a German Dictionary

German dictionaries come in many shapes, sizes, price ranges, and language variations. They range in format from online and CD-ROM software to large multivolume print editions resembling an encyclopedia. Smaller editions may have only 5,000 to 10,000 entries, while larger hardcover versions offer over 800,000 entries. You get what you pay for: the more words, the more money. Choose wisely! But its not the mere amount of words alone that make a good German dictionary. There are a few other factors that need to be considered. Here are a few tips on how to pick the right dictionary for your German learning. Consider Your Needs Not everyone needs a German dictionary with 500,000 entries, but the typical paperback dictionary has only 40,000 entries or less. Youll get very frustrated using a dictionary thats not up to your needs. Note that a dual-language dictionary with 500,000 entries is actually only 250,000 for each language. Dont get a dictionary with fewer than 40,000 entries. One Language or Two Monolingual, German-only dictionaries offer several disadvantages, especially when you are just at the beginning of your German learning. For intermediate and advanced learners they might serve as additional dictionaries to broaden ones ability to circumscribe certain things. While they usually contain more entries they are also very heavy and impractical for daily use. Those are dictionaries for serious language students, not for the average German learners. If you are a beginner I strongly recommend that you get a German-English dictionary to be very clear about what a word might mean. Take a look at a few Buying It At Home or in Germany At times I have come across German learners who bought their dictionaries in Germany because they were simply very expensive in their home country. The problem often was that those were English-German dictionaries, meaning they were made for Germans who were learning English. Which had some huge disadvantages. As the user was German they didnt need to write the German articles or plural forms into the dictionary which made those books simply useless for German learners. So be aware of such issues and pick a dictionary that was written for learners of German as a foreign language (Deutsch als Fremdsprache). Software or Print Versions Even a few years ago there was no substitute for a real print dictionary you could hold in your hands, but nowadays online German dictionaries are the way to go. They are extremely helpful and can save you a lot of time. They also have one huge advantage over any paper dictionary: They weigh absolutely nothing. In the age of the smartphone, youll always have some of the best dictionaries right at hand wherever you are. The advantages of those dictionaries are just amazing. Nevertheless, about.com offers its own English-German glossaries and links to many online German dictionaries that can still be quite helpful. Dictionaries for Special Purposes Sometimes a regular German dictionary, no matter how good it may be, just isnt adequate for the job. Thats when a medical, technical, business, scientific or other industrial-strength dictionary is called for. Such specialized dictionaries tend to be expensive, but they fill a need. Some are available online. The Essentials Whatever kind of dictionary you decide on, make sure it has the basics: the article, which means the gender of nouns, noun plurals, genitive endings of nouns, the cases for the German prepositions and at least 40,000 entries. Cheap print dictionaries often lack such information and are not worth buying. Most online dictionaries even provide you with audio samples of how a word is pronounced. Its advisable to look for a natural pronunciation like e.g. linguee. Original Article by: Hyde Flippo Edited, 23rd of June 2015 by: Michael Schmitz
