Not sure if this is the correct place for this but the Petroleum engineer section seemed to be for exploration so here goes.
We have a gear box that we have been using for a while now. We had been using oil in it but the manufacturer suggested using grease. We switched to the grease he suggested...
I am interested in the correct weld symbol for a flair-bevel weld where the weld is expected to be flush with the material when finished.
The question that has come up is if the throat dimension is needed if you indicate that the weld finish is flush. I have always added the weld size to my...
I know that the Cold Rolled material has a higher Yield Strength due to the work hardening during the forming process. However is that strength throughout the material or mostly around the surface area? And if so how deep would you expect the work hardening to effect? The question came up...
I am preparing a product to send to Europe. We would like to replace all of our decals with wordless pictographs. I am having a hard time coming up with one for a Main Breaker on our control panel. Does anyone have a suggestion of where I can look for the appropriate symbol?
Thank you

I am attempting to calculate the buckling strength of a hydraulic cylinder and have a question. My book shows that I should use the weakest moment of Inertia section bu8t it would seem that that would be inaccurate. The rod inertia is about 1/4 of the tube. So the question is, do I figure the...
All,
We manufacture diesel powered construction equipment and sound attenuation has been a growing concern. We could either hire someone to come in and make suggestions, or we could have someone learn about the concept. I would like to learn about the task so we can do the job in house. Can...
Hi all,
We manufacture small trailers(1,500 to 3,000 lbs) and have just received in a container of wheels that do not mate to the hubs of the axles correctly. It appears that the center of the disk was rolled too far in when punched making the hub to disk mating surface be exclusively the inner...
This is probably a trivial question for those of you with experience but I would like to avoid a dumb mistake. I am attempting to select the correct wire gage to run a 12V motor. This is a 1//2 hp 45 amp (FLA) with a 30 min. duty cycle. The power cord will be 25'. The American Wire Gage table...
OK, this is kind of embarrassing but I haven't dealt with this topic for some time so I wanted to check that I am going at this right. I have a plate of 3/8" A36 steel with a 1" dia. hole centered 1-3/8" from the edge. A load will be hanging from a bar inserted through 2 of these plates. To...
Our company has been using 01 tool steel (meets ASTM A-681) for stop blocks in an application we have. We are now looking to make the flip lever that goes between the stop blocks out of the same material. What is the procedure to use for welding a block of A-681 to a DOM tube? Other than asking...
I have been asked to look up the requirements for lighting on ag trailers that occasionally get pulled on the highway. Particularly as regarding the light colors of clearance lights and stop/turn/tail lights. I would look on ASABE but I am not a member. Is there another place to look for this...
How would I go about determining the required volume of air inlet for a radiator? I am tasked with determinimg if the air scoop opening is large enough for the Cummins diesel engine we are using.
I am assuming a simple bernoulli formula would be in order. Presure in would be atmosphere but would...
