McMaster-Carr has a gizzion parts in their catalog. Rather than use an internal company part number, ex. 123456 for a part and then reference the McM part number, has anyone used the McM part number itself?
For example, one has a bolt with a given thread, material and coating. What if you...
I downloaded a 30 day trial of VX Innovator CAD to have a look-see. I haven't found much in the way of online forums.
Anyone use VX for general mechanical design/drawing CAD use?
Any opinions/advice would be appreciated.
Thanks!

With regards to an AC electric motor, if the locked rotor amps (LRA) are known, can one expect the inrush current at start-up to be higher if the motor is starting with a load present vs unloaded? How would this be same/different with a single vs 3 phase motor?
Thanks!

I use SW on my day job and Alibre (AD) on the side. While I like AD, my opinion is they are slow to implement enhancements that have been in SW for years. Recently, they dumped a nice file management system for something I regard as very complicated for a one man operation.
Another nice thing...
I have an electric heating strip. Let's say the heater's watts is 1000. The voltage is 208. From W=(V^2)*R, I determine that the resistance for the heater is 43.26 ohms. Is this correct?
If I change the voltage to a higher or lower number, does the resistance on the heater stay constant...
I need to know the basic differences between A vs C weighting when measuring sound. I am measuring sound for an outdoor event and in my searching I find a lot of stuff for A-Weight, but little on C-Weight.
When measuring sound with the above weighting, when would one use slow vs fast settings...
Back in my old days of Unigraphics, there was a command similar to SW's hide and show commands - except that all items that were hidden, at the click of a button, would be shown and all items that were previously visible were hidden. Sort of a reverse hide/show command. In UG, I believe it was...
I am considering the following refrigerants for a high ambient application - replacing R-22. This is a new design and I can select what ever refrigerant I want, so long as it is a non-ozone depleting refrigerant.
I gather R-410a is a suitable replacement for R-22 and better in performance than...
What are your opinions of using Schrader fittings on a R-410a system in general and more specifically for a place to mount pressure switches vs brazing. The idea is - in a tight package, it is easier to replace a defective pressure switch that's fitted to a Schrader fitting than tear the unit...
How does the volume of diesel fuel change with respect to a change in altutude?
My preliminary thought is that given it is a fluid, it is considered incompressible and therefore any expansion as the altitude rises above sea level to 10,000 ft would be very small if any at all.
Anyone have any...
I have a about a 3.5 inch tube connection that needs to be plugged with a threaded plug. The tube and plug threads are 3.5-10UN. Tolerance is 2A and 2B respectively. The tube material is aluminum, 6061-T651. The plug material is brass C360 half hard (H02) temper.
The idea of different...
I have an applicaiton that requires a custom made radiator for a diesel engine. Our current engine supplier uses a radiator manufacturer that is at best, lacking in support and turn-around. I am in search for suggestions for an OEM manufacturer of radiators to custom specs. Qty's can range...
I've been tasked to design an enclosure that is to be subjected to vibration. That vibration will be looked at by our FEA guy and at the end of the day, on a vibration table. I have never really designed a mechanical enclosure for vibration - but have design lots of stuff for static loads...
