    Engineering Mentoring

    An interesting paper I stumbled across. I was lucky enough to have a pretty good mentor myself when I got out of school. Any good mentor stories? Are there still people and companies willing to take time to mentor these days? http://www.jflf.org/pdfs/papers/mentoring.pdf

    High Temperature coating

    We use mild steel fixturing for our brazing line and are looking for a high temperature paint or coating to help prevent oxidation of the fixturing, which is exposed to flames about 1800 deg F. The parts being brazed are for food processing, so I'd like to avoid anything with cadmium or other...

    Standard Broom Threads

    Does anyone out there have specs for threads on standard broom handles? I have two different thread sizes, both appearing to have something close to ACME thread profiles but not standard TPI. Most popular is about 3/4" outer thread dia x 5 TPI. Another flavor is about 1.080" outer thread dia...

    Engineering Education: Too Narrow or Too Broad?

    I've had discussions with many friends about the merit and return on investment of a college education. Engineering is one of the few 4-yr degrees that offer relatively high job placement and salary right out of school. Most liberal arts majors must spend more years and $$$ geting masters and...

    Foundation Design for Large Lateral Load

    Does anyone have any references or suggestions regarding foundation design for industrial or marine equipment with relatively large lateral loads, such as winches or mooring bollards? Many installations are retrofit. "Deep foundations" are not acceptable, generally they use a very...

    Material Combos with High Stick, Low Slip Friction

    I'm looking for a material pair that has a high coefficient of static friction and low coefficient of sliding friction. The actual coefficients are not critical, it's the difference between the two that I want to maximize. I'd prefer dry contact unless there is a lubricant available that...

    Bell Design / Acoustics

    Does anyone know of a program or method to design bells given input such as major dimensions, material properties, desired fundamental frequency, etc. A program which would output the profile as a set of data points would be ideal, but a graphical or numerical method would work as well. These...
