    How to calculate permanent load?

    The structural load is just the weight of the bridge "smeared" over the area, often with some factor to account for it weighing more (or less) than you think. What do you mean by non-structural? People walking on it or decorative panels. Permanent loads typically means just the structures weight...

    Second area of moment

    Also, if you tell me the loading, what the material is (E), and what the moment of inertia (I) are, I can tell you how much the member will rotate and deflect. E and I are critical to making the jump from forces to some form of deformation. Euler-Bernoulli is actually a simplification that...

    Engineering Degree Pursue

    You won't really have to pick until your junior year of college. If your parents are really going to be that upset just say your doing mechanical. Even if you do Civil they have no way of knowing. You could probably even do both depending on the universities rules. Why do your parents care so...

    Engineering Why did you decide to become an engineer?

    When I started college I got a job in the structural research lab where people would bring in full sized bridge girders and parts of buildings and I got to break them. It wasn't even my job to do all of the boring post processing work. I've graduated and am at a different university now, but all...

    Small engines vs. big engines?

    I frankly don't have the faith to buy a turbo charged engine from any manufactures currently. Its one thing is they turbo charge a 6+L diesel engine, but its quite another to turbo a small engine. Yeah sure when everything is working great the car and engine is amazing, but if anything is out of...

    Does a wind farms unpredictability lead to a waste of energy in other power plants?

    There are regulations telling companies how much power they have to have on spinning standby anyway. That way if something suddenly happened at one power plant, another would be able to take over a significant portion. A lot of this stuff got revised after 9/11 when threats to infrastructure...

    Car shopping as an Engineer.

    I bought a GTI, and I will never by another VW again unless it is fully covered under warranty. Its a really nice, fun car, but I get so incredibly mad with VW's engineers. They have to be straight out of high school they are just so stupid. I do not understand how anyone can launch a car know...

    Civil and Environmental

    Nearly every example you gave for what an environmental engineer does requires at least one other discipline. To say all, or even most environmental engineering jobs are more sciencey is either an over statement or just plain wrong. Every environmental engineer (except my professor studying meth...

    NEST Teams

    Does anyone know anything about getting on these teams or even what they do. Everything I've been able to find more or less says they respond to nuclear incidents. I like physics but I don't what to be a professor, and I'll finish a degree in Civil Engineering and I hate engineering. I'm...

    Help Big engineering issue

    I'm not a professional yet, but poor planning and no ability to work in a team makes for a terrible engineer. Strangely enough, this is exactly what you will find in many engineers that work at universities (professors or not). I'm sure there are exceptions to this rule...just not at my...

    Tapered beam deflection problem

    Thicker web means the web is wider. Deeper web means the section is deeper. In some cases, the web is the only dimension that changes. The flanges in most precast concrete girders are kept the same to facilitate precasting and spacers are added to increase the depth of the section. If you make...

    Environmental Engineers

    I'm fairly sure any government project in the US requires this but I don't think private projects do yet. Another fun thing environmental engineers get involved in, is urban land usage. The more impermeable land you have in a city (land covered in concrete so water can't be absorbed by the soil)...

    Tapered beam deflection problem

    The thicker web does not mean a taller cross section. The web is the part that connects the two flanges in an I beam. They could use the thicker web for several reasons and with out knowing the specifics its hard to tell. You use the taller section because you give yourself a longer moment arm...

    Prospect of Engineering?

    I know a civil engineering professor that makes well over 150k and I know another engineer that makes about 30k. I think engineering is such a great field because your efforts usually result in something tangible like a bridge or building. Infrastructure engineering is probably going to see a...

    Environmental Engineers

    Environmental engineers are a subset of Civil engineering. In a sense, their job is to fill the gap between scientists and other engineers. Typically they have a much better understanding of chemistry and biology than your typical engineer. Most of the environmental engineers that I have talked...
