Like was already stated, the fluid will most likely not help the balance. The only way I can imagine that working is if the imbalance was solely due to runout of the ID (internal diameter). The closer the density of the fluid to the density of the metal, the closer you could get the balance...

I think the question you are trying to ask is just whether you can see different frequencies independently in the FFT, and the basic answer is yes. The whole point of the FFT is to allow you to take the time based signal and show it as the component frequencies. Within the limitations of the...

Clarification: Every spike that you see in the FFT is not necessarily a harmonic. A harmonic is a multiple of a specific frequency, which is to say that it is twice (2X or 2 times) or thrice (3X or 3 times) the frequency of the fundamental frequency (datum frequency) that it is being compared...

Probably busy working

The traditional pencil and paper, 8 hour, two part FE exam has just finished its final iteration. Starting in January the tests are now 6 hour, more discipline specific, computer based exams. I still believe it's up to you as to whether you choose your own discipline or the other disciplines...

It has always bothered me, and soon I will take my place on the second side of the issue when I graduate with my BSME in May. The reason it bothers me, is not that I believe I should deserve any special status or respect (after I graduate), but that the descriptor should serve to convey a...

To elaborate on what has already been mentioned, and to throw further wrenches into your assumptions... My starting salary is 1.66 times the national average for my degree type and almost 50% of the workforce where I will work is eligible to retire in the next 5 years. I'll qualify that I'm 30...

I have two Rotring 600s and a Rotring Rapid Pro, all 0.5, that I switch between for daily use. I kept a Pentel P205 around for when I'm not going to be sitting in one secure place because I've already had a couple of tips bent on the 600s. I like the weight and feel of the heavy metal...

I ran across them a few years ago when deciding on what trees to plant. But even here in Houston, those beautiful trees won't survive the winter. I guess if I want them one enough I'll have to move to the Keys or Hawaii. If you ever visit Maui, they are pretty easy to find, especially on the...

I'm not sure about plain ol' dumb or incorrect statements, but the main one that comes to mind was about two years ago in my Dynamics course. The professor was deriving Kepler's 2nd Law and made a mistake in his implicit differentiation. When a student in the back asked about the mistake...

It can certainly change, although it's not likely by choice. More detailed tests can show how well an individual can adapt to different/opposing traits, and how much stress is involved in deviating from the natural traits. Major changes in a persons life can have large impacts, including...

Any work experience will be good for a few reasons. 1) To look good on a resume 2) To expose you to the work environment, whether it will be similar to life after graduation or not. That said, there's no way to know how specifically, technically useful an internship will be to your future...

To further expound on this, I was going to use Josiah Willard Gibbs as an example. He was awarded the first PhD in engineering in America, and contributed quite impressively (understatement) to many other fields.

For an incompressible fluid with a single inlet and exit the conservation of mass equation simply reduces to volumetric flow in equals volumetric flow out. It is then immediately clear that with a change in area from the inlet to the outlet, there is a corresponding change in velocity. The...

It certainly looks like homework, but beyond that you should have provided the original problem. To me, it looks like you applied the ramp incorrectly, but I can't be sure without the original problem. Is that your transfer function on the left that you tried to apply a ramp to? My suspicion...
