How does the properties and structure of an engineering material affect their behaviour engineering in given engineering applications?
Need help on this. Can anyone explain and give me a reason why?
Question answered by Stephen
The mechanical properties of a material greatly affect the behavior of a structure. Steel and all other metals are what we call an isotropic material. This means that the mechanical properties of the material are the same in every dimension. Think of a solid steel cube. If you apply a uniaxial compressive load to the top of the cube, it will behave in a specific way. If you apply a uniaxial tensile load to the top of the cube it will behave exactly as the previous case. If you repeat these steps on the sides of the cube, it will again behave the exact same as before. Concrete will not behave in such a manner as it is poor in tension and great in compression. We call this material anisotropic. Other materials such as composites (Glass Fiber Reinforced Polymers, Carbon Fiber Reinforced Polymers, etc.) are designed by material scientists by embedding a fiber reinforced laminate in a resin based matrix. They can arrange these laminates in a variety of dimensions to attempt to give the material nearly isotropic properties, but this is never the case with composites and they mainly end up being anisotropic. This is ok, because the designer knows this and so uses the composite in such a way that it's strong axis is always utilized in the direction of the load.
With all this being said, there are dozens and dozens of material properties that you can learn about. However, no two are more important for a design engineer than the Elastic Modulus and the Tensile Strength. (Shear Strength comes in at a close third, but I am a Structural Engineer in the Civil Field, so.......) The Elastic Modulus is what governs the amount of deflection a member will experience under a given load. Steel has a high elastic modulus, Plastic has a very low elastic modulus. Therefore, if both were fashioned into a beam of equal dimensions and loaded equally, The Steel beam would deflect a lot less than the plastic beam. The tensile strength is also important as it governs when a material will yield or fracture. If you continue to load both beams, the plastic beam will fail first since it has a lower tensile strength. There are some materials such as composites that have low elastic modulus yet high tensile strength. Just because a member is deflecting a lot doesn't mean it is about to fail.
What are five (5) timber products that have shifted from conventional timber products to engineered materials?
The use of timber and timber products has substantially changed from their traditional use in building. The need to conserve our native forests and provide economical solutions to building has led to a shift from conventional timber products to engineered materials.
Websites of manufacturers also requested if applicable.

New Engineering Materials/New applications for materials that have been around?
I'm in an introductory course to building construction materials and one of the goals of the course is to write a technical paper on any new engineering materials (5 years old is still considered new according to my professor) or any new applications for materials that have been around. Does anyone have any information/knowledge on where I can get started? Links,books, scholarly journals would be appreciated. Thanks

Engineering materials? Maybe engineering field of studies. Please clarify.
why does the american military continue to use poorly engineered material?
compared to most modern armys the american military has always had "obsolete" weapons. why do they continue to produce and use terribly engineered material. a perfect example being world war 2 every thing the Americans had all the other countries had it and it was better (excluding nuclear weapons)
Question answered by Curt J
If the M1A2 is obsolete, what does that make every other tank i the world, to say nothing of the F22?
Also, during WW@ we had the B17, P51, P38 and towards the end, the B29, none of which were inferior to anything else in the air
What engineering majors do you think need to take this course at this 2 year college?
I don't think all engineering majors would benefit by spending time in this course, but I could be wrong, this is the class and description:
Engineering Materials looks at typical materials used in engineering like different types of steels, concrete, etc and looking at the strengths and limitations of each.

Question answered by TMart
From experience civils, mechanicals, and nuclear engineers tend to take the materials courses. There could be others depending on the content like electrical engineers and biological engineers.
How do I get the best grades in these engineering classes while being present as little as possible?
This fall, I will be returning to my engineering studies in an effort to complete my degree in engineering. I would like to get a list of tips/methods to use to succeed in the following classes while earning a high grade and being present as little as possible (because of tuition costs/gas prices/missing work issues since I am required to work 40 hours per week). I must have an engineering degree in order to receive a raise at work, which is strongly related to engineering. Here are the classes:
Soil Mechanics, Fluid Mechanics, Determinate Structural Analysis, Civil Engineering Materials, anything surveying as far as civil engineering goes. I'd also like to possibly get tips for the classes beyond those in the civil engineering classes, as well as for the upper division/graduate level power engineering/software engineering/computer hardware engineering classes in order to succeed in those classes while maintaining my busy work schedule. Thanks!

I guess you demonstrate the soul of an engineer in your question... it just isn't efficient to go to all the classes!
The advice I offer to anyone in school is that you figure out what it takes to get a B. You need to figure out how each class works (points wise) and how much help you need. To some extent this can help you prioritize, whether to take the easy "B" (when you see it) or bust out extra effort to get an "A".
Building a good network of friends in your education program. They can clue you in to missed lectures, advise you on the best professor choice for a class you haven't taken yet, and help you out when you need a study group.
Talk to any coworkers who've completed similar work recently and solicit advice on order of courses. If you've been out of school a while, use this summer to work on the drafting, math, programming and calculator skills that you'll need.
In your first term on campus, invest the time to meet people and learn how to get things done around there. Make friends with other commuters as well as with full-time students. Your real-world experience will be valuable to them (advice on projects, practical examples of theory, etc.), and they will know a lot more people on campus to help you out.
It also won't hurt to sniff out your boss' tolerance for doing homework on their time. This would be a great year not to participate in Fantasy Football ;)
What does the general Engineering major cover compared to more focused disciplines?
One can be a mechanical engineer, materials scentist/engineer, or any of various disciplines. But what do you learn in the non-specified engineering major?

Is it hard or easy to learn engineering statics, dynamics, and strength of materials on your own?
I feel that physics, statics, dynamics, strength of materials, engineering materials, fluid mechanics are very important subjects to learn. I believe having a good understanding in these courses will help you out in the real world a lot. That's why I'm asking this question.
Question answered by oil field trash
It depends strictly on the ability of the individual and the quality of the subject matter they use. Good subject matter with lots of problems with answers can be very helpful.

it's not that hard buddy but if ur good at software and programming just go 4 it , but if ur good at hardware u should go to computer eng. , and 4 me I like the motors and these stuffs so I joined the mechanical eng. think twice bro befor chooseing .thanx
