Chemistry in Engineering
In today’s society chemistry is greatly involved in the world of engineering. Whether it is aerospace, mechanical, environmental or other engineering fields the makeup of substances is always a key factor which must be known. Engineering today has morphed from only dealing with the physical aspect of the field into the theory behind the field. All engineering fields have unique bonds with the chemistry world. We will discuss many of these bonds in the pages to come.Being the most interesting field of engineering, and the fact that it’s my major we will talk about Aerospace Engineering first. Aerospace was devised so that we could further our knowledge in the field of aviation and space flight. When the Wright brothers designed their first fixed winged aircraft they had to understand the concepts of lift, drag, and thrust. Aerospace engineering deals in depth with these three concepts and more. With Boeing and other companies now producing aircraft as large and bigger than 747’s the engineers must find ways to make the planes lighter and more efficient as they become enormous. New alloys and metal compositions must be discovered and new forms of engines must be cre
Other situations in which environmental engineers work with chemistry are when they are looking for solutions to future problems. What do I mean by future problems? Future problems refer to problems that have not yet risen but will come in the future. Some of these problems are things such as global warming and future pollutions created by new fuels. Well, now that five hours have gone by, I have finally hit the two thousand word mark. Whoa, now we are having fun. Anyway, let me get back on topic. The next category of engineering that I am going to talk about is the field known as electrical engineering. Now I do not know a lot about this field but I do have many people in my family that actually have electrical engineering majors. From what I have heard, electrical engineering deals mainly with the circuitry of computers and everything that a computer needs to run properly. Electrical engineers are always looking for a way to make systems run faster and much more efficiently. They try to create a circuit card that will run at an extremely fast speed yet still transmit the information properly. They also try to keep costs down while making the card still run quickly. These engineers spend much of their time studying electrons and how they move. They try to figure out what the best temperatures and elements of weather are for when the chip will run the best. So once again I will bet that you are wondering how this has anything in this world to do with chemistry. Well, here is the answer. Chemistry comes into play when temperatures and elements that conduct electrons at certain rates. EE’s also must find certain elements that will not conduct current so that they can make resistors. Electrical engineers must also find elements that will partially conduct electricity. These items are called semi- conductors. Electrical engineers are very important to today’s society because power and electricity are required to run almost everything in today’s world. Without these individuals and their expertise, none of our computers and circuit cards would be as effective and fast as they are. the item is entered into the computer, tests are performed that will show how the item will hold up to events such as temperature changes and air turbulence, cold nights and warms day, etc. So in the long run engineering technology can be very useful to companies that need to test items but don’t have the proper capital to run actual tests. This job also has great job security because large companies will always be looking for ways to meet the proper requirements yet save money at the same time. All big businesses run in a way that allows them to have a great profit to expense ratio. As long as the world is relying on money to run businesses, there will always be a place for engineering technology. Another engineering field that deals intensely with chemistry is the environmental engineering profession. This profession deals with solving environmental problems and preventing new hazards from forming. Without the work of environmental engineers, the earth would become so polluted and toxic that it would not be habitable. Everyday, environmental engineers go out into the world and try to make it better. They make improvements by doing studies and seeing where improvements can be made. After they complete their experiments, they go back to the lab and analyze the results. After doing that, these engineers will contact the people that can help make a difference. This can include a number of people. Public relations people help let the world know what is going on and how the average person can help. So you’re probably wondering, how does chemistry actually deal with engineering? Well, chemistry is used by environmental engineers everyday. Environmental engineers are active in nature; they go out into the real world and find where improvements can be made. Chemistry plays a role in the actual solution. These i
