Davids, K. (2010, Mar 22). Simple car maintenance advice for mechanical novices. From http://www.a1articles.com/article_1460706_31.html

Summary:
Some people lose a lot of money for the maintenance of their cars, and the reason is lack of knowledge. We must learn at least the basics for the maintenance of our cars, to protect them and save money. These are some of the basics of car maintenance, such as tires and wheels, one of the most important parts of the car that must be maintained and monitored; we must also clean the brake from dirt and dust. Also we should buy a tire that applies to the legal requirements, to avoid an accident, God forbid. Although we can save money by monitoring the air pressure in tires because if the air pressure is incorrect, it increases the resistance and increases the amount of fuel consumption. Some of these fundamentals include checking the coolant level to maintain the engine, and checking engine oil level
Reaction:
Most people have cars, so they must protect their cars. In particular, they are protect them through regular maintenance, which does not cost them much effort: I know people do not care about their cars and they just fill them with fuel, and this itself is a major problem with regard to safety and saving money. However, there are many car components such as electrical components and mechanical components and structural components, and these components require knowledge and learning about them. But the basics of car maintenance may be the most important of these components because if we check of our cars by regular maintenance we can protect them from the lot of damage you may get it.

Summary:

Solar cars are cars that use the sun for energy. They run by converting sunlight into

energy. The electrical system is the significant system of the car, because it is what converts sunlight to energy. The mechanical system is difficult because it needs to be strong yet light weight. This is now achieved with composite materials. The ratio and weight is not the only factor, price is also important. Solar cars are beneficial because they do not use fossil fuels and they reduce pollution. But, they are limited in speed and power, and are only practical in areas with a lot of sunlight.

Reaction:

I believe solar cars can be a big help for the environment. They create less pollution and reduce the amount of oil drilling needed. Most important is the battery. Since batteries only have a limited life it will reduce how much people want them. However, people who live in areas with a lot of sunlight will find them very useful. It is only a matter of time before a way is found to store the energy for longer and make it easier for everyone to use them. I also think the things advance quickly and now that people see pollution as a problem more money will be spent to improve the technology. I think it is time for electric cars because the more people drive and buy them the more they will work to fix the problems. Besides, people are learning how bad pollution is, so they want to fix it and these cars could help.

The Future of Solar Energy

Khemani, H. (2010,Mar. 15). The Future of Solar Energy. From http://www.brighthub.com/engineering/mechanical/articles/5785.aspx

Summary:

Solar thermal power plants are still in the process, which is being developed to help solve the energy crisis and electricity generation in particular.That is because the fuels used in generating electricity and thermal energy are expensive and causing environmental pollution. Whereas solar power is plentiful and does not create any pollution, there is a problem in its use, because it works only in the day and there are also influential factors, even in the daytime, for example, when the weather is cloudy. But scientists are still trying to solve these problems, and there are stations for solar power still in process of trial and error detection to create an environment free from pollution and energy at lower cost.

Reaction:

I hope that solar energy can replace electricity, which is expensive and causes pollution, or be the generating electric power. I expect in the near future there will be solar energy, alternative energy, which will be used in the automotive industry and in factories and homes in general. Also the cost of producing solar cells are expensive, but it is very useful in protecting the environment. It is expensive because the competition is minimal and most of governments in the world will not allow people to install their own system.

The danger of Air and Bubbles.

Garner, D. (2010, April 15) The danger of Air and Bubbles. From http://www.chemie.de/articles/e/103550/

Summary:

One of the most serious problems faced by the hydraulic and lubrication oil system is the air and bubbles. The air usually enters from the suction of the pumps; it causes foaming inside the system, which indicates the wrong reading of the level. Another problem is the cavitations, which happens in the pumps. It happens when the pressure of the liquid is less than the gas inside it. That leads to mechanical failure, which causes the damage to the equipment. Therefore should watch the entrance of the pump and be sure it is safe; also, it should be changed if necessary.

Reaction:

This is a common problem in the most industries; therefore, every company is trying to reduce this problem as much as possible. For example, they install different types of sensors to keep the equipment safe. And for the foaming, they put antifoam, depending on the kind of liquid, in the system. Cavitations and foaming lead to stopping the whole plant; because of this, operators in the plant should take care to avoid these problems, by taking readings, watching the levels, recognizing any abnormal sounds. The cavitations also cause serious problems like fire and explosion.

RRJ1 (Introduction to welding)

Kristoff , S (2009, Oct 13). Introduction to welding. From http://manufacture-engineering.suite101.com/article.cfm/introduction_to_welding

Summary:

Welding is a process that is used to connect two pieces of metal together, by heating them until they melt. However the gaps are filled with another material like welding rod or wire. There are many types of welding such as Gas Welding by mixing oxygen and acetylene; it is a common type of welding; also it is used for brazing, cutting and heating metal. Another type of welding is called Arc welding; it is working by electrical current. Another type is Spot welding to join small sheets of metal by electrical current. Each of these types of welding has different uses, especially for industry.

Reaction:

This article is un introduction of welding because there are many types of welding for different uses. The welding is like Art; it is very exiting and you have to be accurate. Also you have to take care if you want to be a wilder, because you are dealing with a high temperature and high electrical currents. You should wear a full PPE (Personal Protected Equipments) to do any type of welding. There is a welding underwater which is the most dangerous work in the world.

Vocabulary:

Fabrication- to invent or produce (esp. a story that isn't true) in order to deceive

Combination- together

Brazing-mixing

Invariable-never changing

Appropriate-correct and right thing to do
