Writing assignment reports - Research Paper Example Changes that have been characteristic of the jet engine will also be highlighted, owing to the dynamism of technology over time. Another thing that this report will try to assert is the suitability of the engine in its use, considering its efficiency, cost of use and operation. The consideration of the specific parts of the jet engine is the basis through which the required study can be done in order to ascertain what this report is all about. A jet engine is one interesting machine to study and compute a report on. Air is sucked into the front of the engine by a fan. From there, air’s pressure is heightened by the use of a compressor. This is achieved by the presence of blades within the compressor. The blades found in the compressor are responsible for the increased air pressure within the compressor. After compression has taken place, fuel is introduced in the chamber, and an electric spark used to ignite the mixture. Burning of the mixture consequently makes the constituent gases expand. The blazing mixture blasts out of this chamber through a nozzle that is found at the rear part of the engine. The blasts of gas at the rear of the engine triggers forward move of the aircraft (Klaus 108). All the chambers identified in this discussion are connec ted and given below as an example of the jet engine. The operation ability of the jet engine is purely based on the equal and opposite concept of reaction by Isaac Newton. This is what Isaac Newton referred to as thrust. Gases released through the exhaust after combustion of fuel and the compressed air further finds another role in the process of being emitted. A propeller that is an attachment of the turbine shaft is rotated by the gases for the purposes of fuel consumption saving when the aircraft is at low altitudes. A jet engine is light in weight and also powerful in terms of its propelling force. It is also preferred for

California Clinics - Essay Example This will in turn increase the required rate of return. ii) Time Preference for Consumption: If people choose to consume their income now rather to save, this will reduce the supply of investment capital oblivious to the demand of investment capital at that time. In this conditions, the firm's will find lesser sources lending investment capital and they try to attract more investment capital by offering them higher interest rate and this will again increase the required rate of return from the investment following the higher rate of interest that these firms will be offering. Similarly, if people decide to save now and spend later, this will lead excess supply of investment capital in the market. The firms here will be able to obtain investment capital at lower rates and will enjoy decreased interest expenses. Some projects that were not feasible because of high interest rates in the market will now become feasible and firms will borrow more. However, due to excess investment capital available in the market, the interest rate will decrea se and so as the required rate of return. iii) Risk: Risk requires compensation and likewise it will affect the interest rate of capital of investment. If the risk of an investment is high, then the investors will only be willing to invest in that project at very high interest rates. ... iii) Risk: Risk requires compensation and likewise it will affect the interest rate of capital of investment. If the risk of an investment is high, then the investors will only be willing to invest in that project at very high interest rates. If the risk of a certain project is low, then the investors will be investing in that project at lower rates of return and interest rate. Hence, we can develop a relationship between interest rates and the risk of a project. These two variables are directly related with risk being the independent variable and interest being the variable depended upon risk factor of a project. Any increase in the risk factor is going to increase the interest rate or required rate of return of a project. Similarly, if the risk factor of an investment is low, so will be the interest rate. This clearly shows that risk requires compensation and interest rates vary depending on the risk factor of a project. A logical explanation to this is the fact that very few peopl e are interested in investing in highly risky project fearing that they may lose out their money. As a result, the supply on investment capital is very low for these projects and vice versa. Inflation: Inflation reduces the purchasing power of money. It erodes the purchasing power of people if their money is not invested into projects yielding interest rates which are at least equal to the going rate of inflation. If the interest rate earned is less that inflation, then you are losing out the real value of your money. This means that it won't be able to buy in the future, as much as it buying now. This is a dangerous situation for investors as they are faced with a situation in which the real value of their assets is decreasing. In times of inflations,
