I'm having a hard time finding information anywhere in the literature. Co-workers are drawing a blank as well.
The issue we have, on an existing assembly, is a relatively heavy shrink fit between a gear and an intermediate shaft (width 2.00"; ID of gear Ø3.1880/3.1890, 63 microinch finish; OD of...
Good afternoon everyone,
There is a welded manifold fabricated from 1.5" square ERW tubing and half couplings, it is a collector of a number of case drain lines from some hydraulic pumps. The hoses come together to the manifold because there is a temperature gauge on each line for monitoring...
Please see attached picture. I tried to find the symbolic solution for this trig integral, it gave me a funny solution with all complex terms (L, x and b are distance measurements, P0 is a pressure term). It finds a numeric solution just fine, but I can't get a decent symbolic solution.
Any...
Hello,
What effect does "edge distance" have on lag screw withdrawal resistance in wood? I need a source as well, just let me know your source and I'll look it up!
I found in "Standard Handbook of Fastening and Joining" a chart that was reproduced from AF&PA source, wherein...
Can anybody help, I need to measure the maximum deflection of a large flat panel under an impact. There's nothing really extreme about the situation, it's a mass of 9 lbs impacting at about 50 fps (34 mph or so) and total deflection is on the order of about 3".
Assuming the deceleration...
I need a good structural design reference that specifically addresses anchorage, can anyone recommend one?
My problem is to design an anchorage system to affix window shutters to withstand hurricane forces in Dade County, Florida. Applications will be elevated (dangerous!) and to every kind of...
I'm not a civil engineer so this is an alien topic to me.
I have a conversion calculation as follows:
MPH = sqrt( PSF / 0.00249 )
What I am doing is testing rollshutters for windload using a vacuum chamber. I am able to measure the vacuum inside the chamber in inches of water column, which...
Lately my company has been using Omron PLCs which are programmed using ladder logic. We had this frustrating experience where we were using "out/not out" commands (one per relay, per block). The frustrating thing is, to put all these darn conditions in each individual network to control each...
I am interested if anyone has had experience with spiralock fasteners. I am considering changing out a bunch of my stuff like taps, nuts, PEM-type fasteners and so forth. My principal activity is automation equipment, on my last project I used Nordlock 2-part lockwashers but they're kind of...
I've implemented a central database for our manufacturing and engineering consulting enterprise (3 engineers) to centralize "knowledge" including just about everything: part number lists, bolt count lists, phone contacts, you name it. Right now it's an EXCEL worksheet that is shared across our...
