I work at a community college and doing some bending beam experiments for student labs. When doing simply supported beam deflection calculations and measurements, I am seeing some inconsistent data that I cannot explain.
If I test a basic cross sectional shape (square, rectangle, tube), I get...
I am advising a group of college students on the development of a electical motor/combustion engine hybrid vehicle project. We are all very new to this field.
I am looking for textbook and resource recommendations to educate ourselves in this technology.
As mechanical engineers, I am...
I am developing an intranet website for our engineering department and would like to include a section on helpful websites for engineers...things like online calculators, design resources, standards..etc. We are mainly mechanical engineers and do alot of machine design with motion control...

I am doing rotor interia calculations for some rotor assemblies in a brushless DC motor. In the past I have always ignored any effect due to front and rear bearings. I am beginning to question this assumption. Does anyone know if this a valid assumption, and if not, some insight on how to...
Does anyone know of some internet resources defining NEMA motor frame sizes (i.e. physical dimensions for bolt patterns, shaft size etc)? Some searching around on general purpose search engines did not prove successful.<br>
I currently have a couple thousand Pro/Engineer models/assembly/dwgs that are version 19.0 or earlier. We have recently upgraded to version 20.0. I am curious how other Pro/E users handle their upgrades with respect to coverting your files to the latest revision. Do you only upgrade the files...
We currently use 1144 steel for motor shafts. This material is not the easiest to machine and we are considering a different material. My initial inclination is an 11L41. It has a higher machinability index with similiar material properties. The material must also be magnetic. Does anybody...
