"I am probably wrong because what I want is just not how anything is run these days." I think you're spot on with that. I don't think you're going to find high impact and large projects in the same role especially as an intern or eventual recent grad. It's just not practical. Usually anything...
From the picture I can see two points of rotation. The top one looks like it is geared down once from the servo. The one on the side looks like it is probably direct drive as you said. The picture's not very big so it's hard to tell. As long as you size your servo correctly it shouldn't be an...
I would take a look at something in the ASME B30 series. I'm not sure exactly which ones because I don't have access to all of them and I'm not sure exactly what your applications are.
Based on my limited knowledge of cranes, you have to re-certify them after changing anything related to the...
Since solar panels that do everything are all the rage now, we should get some of those to put on roofs. They will be solar panels of course, strong enough for people to walk on, and textured for traction. They can melt snow on top of your roof in the winter so Santa doesn't have any issues...
I rarely keep up with news but I saw this on CNN and thought it looked really interesting. I'm always skeptical of these "green" visionaries trying to change the world, but this guy's an EE of 20 years, has been working with several universities, the US Federal Highway Administration, and more...
Thanks everyone for your input.
Part of the problem is that the thread is 1 1/4-5 which is not a UNC thread. It might be Acme because Acme threads come in that size but I don't have an Acme thread gauge to check. Even if it is, I haven't been able to find Acme locknuts anywhere, much less all...
Does anyone have a good way to add resistance to turning to a threaded rod? I’m not sure prevailing torque is the right phrase as I’ve only ever heard it in reference to locknuts but that’s the concept that I’m going for.
Basically I have a 1 1/4-5 threaded rod with a nut on the end that goes...
It's not clear to me, but if that's the 4th week after the invoice date, good luck with that. I have yet to meet a company that pays their invoices before the due date. You'd likely be annoying a lot of clients who pay things right on time.
Can someone explain why one would need a filter in a closed loop system?
I was just involved with putting in some new equipment. The equipment is cooled by a chiller with a water/gycol mixture in a closed loop system. All the piping is PVC or stainless. The chiller manufacturer doesn't include...
"if you make the roller tube a solid bar, what'll happen when the two substantial things bash together ??"
That's part of why I want to calculate the strength of the hollow roller. So I can get an approximation of what kind of forces I'm dealing with.
"the roller is in the right spot ?"
Yes...
chicopee & dhengr,
Sorry I can't post a picture of the larger tube because it's a highly proprietary process. The reason it deformed so much is because it's part of a custom build machine and there's extra force applied on top of the larger tube. I know exactly what's causing this and nothing...
Tmoose,
"the dent in the picture appears to have a uniformly curved bottom."
That's correct. Not an illusion.
"It also appears to have been "dented" so the tube is about half as "deep" as when it was round."
Significantly less height but not half (see picture)
"It was created when one (larger...
Yes I suppose that's an element to it. But the fact that the conveyor is hollow, the tubes are perpendicular to each other, and the conveyor roller is not fully supported makes it much different than any of the contact situations that I'm familiar with or that I have formulas for in any of my...
Hi all
I've browsed this forum for a while, have found it very helpful, and recently decided that I'd like to get more involved.
I have a conveyor that I'm rolling things across. Recently some excessive forces were applied to the top of one of the rollers by another tube on top of it and I...
