    What's going on with Acetone and ABS chemically?

    In 3D printing it is a well known trick to use Acetone to smooth/dissolve prints made from ABS plastic. Most articles call acetone a "solvent" of ABS but after some experimentation with PLA plastic and THF "solvent" I get the feeling "solvent" may be too vague a term. The main observable...

    Airfoil Design Research

    Does anyone know of any types of research out there that attempts to establish analytical ways to design an airfoil. As far as I understand it right now, when someone wants to design an airplane they grab some premade airfoil shapes and test there design empirically using CFD or a wind tunnel...

    Engineering Engineering, should I show off work from my current job in an interview?

    Have kinda of an ethics question here. I work for company A and have an interview with company B. Company B would like to see examples of my work, which is mainly 3-D models of designs and technical drawings. However these things are technically the property of company A. Also I don't want...

    Ph.D and a career in teaching Community College

    So if I wanted to change my career from professional engineer to community college teacher, would a Ph.D in engineering be helpful or over qualify me? I have a bachelor's in Mechanical Engineering, a M.S. in ME with emphasis on controls and dynamics, and about 2 years of professional...

    Simple (or not so simple) Momentum question

    I've been thinking about basic momentum problems lately I'm having a surprising amount of trouble with one that didn't seem so bad at first glance. Here's what I'm imagining: We've all heard of the simple momentum problem where a particle moving in the x direction at speed v1 runs into some...

    Getting a job in a new venture company.

    Hello, I'm a mechanical engineer graduate with a little over a year of real world job experience. This first job has been rather disappointing for me so I've been giving my long term career goals much more thought. I originally thought I'd want to get a Ph.D and perhaps do research but what...

    Ph.D in Nuclear Fusion power?

    Hello, I'm a Mechanical Engineering grad with a M.S. in Controls and Dynamics and have been working for a year. I was originally set to get a Ph.D in Controls but I kind of got burnt out on being a student and settled for a M.S. (would have just left but it took so long to find a job I ended...

    Does anyone do this type of Aerospace Research?

    Hello I currently hold a M.S. in Mechanical and Aerospace Engineering and a B.S. in Mechanical engineering (note the M.S. had an emphasis in controls and dynamics). I got my M.S. by only taking grad courses and have done no research or advanced project, I graduated last year and have been...

    Any universities do this type of research?

    Hello, I'm a former grad student with a Master's in Mechanical Engineering (emphasis on Dynamics and Controls) and I'm thinking of going back to school for a Ph. D. I'm very interested in technologies involving the use of endurance UAV's (UAV's designed to stay in the air for weeks at a...

    Calculating forces on a rotor

    Hello, Out of curiosity I've been trying to mathematically model the forces on a rotor during auto-rotation starting with the basic lift/drag equations used for analyzing basic fixed wing flight (i.e. our beloved L = 0.5*Cl*rho*A*v^2). At first I thought this shouldn't be too hard since it's...

    Should I follow up job applications with a phone call?

    Hello, I'm a Mechanical Engineering grad student (got my B.S. in ME as well) and I've started applying for jobs. I've heard that it's a good idea to call the company after sending them a job application but I just can't think of what I'm suppose to say. Do any engineers in the workforce has...
