    Hamiltons Principle on Moving Cart with Fixed Beam

    Homework Statement -Use Hamiltons Principle Homework Equations \int _{t _{1}}^{t _{2}}({\rm }\delta T -\delta U -\delta V _{E }) dt} The Attempt at a Solution Here are my energy equations. So we have kinetic energy from the base and the beam. T_{{{\it beam}+{\it base}}}=1/2\,\int...

    UCLA or UMN for graduate energy study/research

    I should also add that the ones that got the fellowship did research with the same professor during their undergrad. If you want to still do research as a grad student, you still can. It may or may not count for anything, but I've seen rules bent several times. They may pay you or they may not...

    UCLA or UMN for graduate energy study/research

    I know a few that are doing the thesis option for the M.S.; however, they did their undergrad at UCLA. Therefore it was somewhat easy for them to get fellowships since they already knew the professor for some time. From what I've heard, most of the professors don't want to work with M.S...

    UCLA or UMN for graduate energy study/research

    I'm a grad student in the ME program a UCLA. I think we have a pretty good program in terms of Fluids, Heat Transfer, and Thermodynamics. The only problem is the budget cuts are really hurting us. Therefore class sizes are getting much bigger for the grad classes, and some grad classes (not the...

    Near and Far Field Attenuation Inverse Laws

    Maybe I was thinking too much and thought there was more to the proof than just doing 20log(1/d^3) and 20 log (1/d). Thanks.

    Near and Far Field Attenuation Inverse Laws

    Homework Statement near-field distance attenuation follows an inverse cube law (1/d^3), while in the far-field it follows inverse law (1/d). Prove mathematically how we arrive at 60dB/decade from the inverse distance cube relation and 20dB/decade from the inverse distance relation...

    Choosing your TA's

    Just wondering how the educators out there or departments choose their teaching asisstants. In my department, if faculty is teaching the course, then they tend to use their own students from their lab. If it's an outside professor, then the faculty professor in charge will probably ask HR to...

    Anyone else take the fundamentals of engineering (FE) exam yesterday?

    Yea I took it at the exam site in Pomona yesterday. I thought there was alot of mechanics ( strength of materials) type of questions on both the morning and afternoon general test. I saw some fluids, and thermodynamics questions. I only saw 1 heat transfer problem and it was ridiculously easy...

    Question About Grade Recording for the Instructors Out There

    I totally forgot that handwriting can be a hint at a learning disability. A few years ago there was this student who would always doodle or write illegibly on his exams or assignments. Luckily for him the problem was caught early and he was always given about an extra hour for exams.

    Question About Grade Recording for the Instructors Out There

    I usually do the alphabetical order method. I found that alphabetizing every paper took a lot of time, because I would run into snags like unreadable last name, none stapled papers, and students who would interchange the order of their names (last, first or first, last). Since I have the whole...

    Question About Grade Recording for the Instructors Out There

    Thanks to budget cuts the class sizes have increased a lot, which makes the class roster on my excel sheet pretty long. After a couple of hours of looking through students different styles of hand writing, my eyes get a little fuzzy and it makes searching for students names on the spreadsheet...

    Career and subject of Mechatronics

    You should look up Control engineering if you want more info on Mechatronics. The professor I had for Mechatronics helped found Innovative Integration Inc. You can google the company and it should give you an idea of what mechatronics can lead to.

    Unknown DC motor Specifications

    It's a DC motor. I'll post what was engraved on the motor on monday. I put the motor in my schools machine shop for storage, and they're not open on the weekend.... Also I'll check if they have a dynometer that I can check out.
