Thank you for the explanation. I was unaware of this caveat with roller constraints.

It would only react moments at that interface if there were any, which there are not. Stiffness and lengths are not needed to solve.

Another clarification I should add: based on the system this represents, the skate roller is in essence constrained to a track so that Fx is always perpendicular to the wall. It can react moments and the system should be stable. I tried to do this in a short-hand way using a perpendicularity...

One quick clarification: Fx is a resulting force, not an input. You do not need to solve for Fx. I drew the vector just to help visualize the reaction force at that surface. Sorry for any confusion.

I am hoping to settle a debate between two engineers. I have created a simple diagram of the part of the structure we are investigating. It can be solved in 5 minutes or less by anyone familiar with static equilibrium problems. The goal is simple enough: find Fn. Yet, the discussion over...

Thank you for the reply. This and similar ideas have come up a few times, and it's one I enjoy. Unfortunately, it isn't possible with our current system.

Looking on LinkedIn is a very interesting idea. Thank you. I don't have much insight into our companies connections, but I will see if any of them might be worth asking. Thank you for the idea. And yeah... I will use this feedback to fine tune my internet navigation protocols.

Our current mission does not aim to refuel the satellite, just take over maneuvering like a jet pack. That way, we can get more usefulness out of satellites that are already up there. Northrop Grumman previously proved the concept with the MEV-1 in 2020 by docking with the thruster bell of a...

Thank you, and my apologies for not explaining better earlier. I am designing grippers for a satellite servicer that will grab onto the remnant LARs of other satellites. Once docked, the servicer can take over maneuvering for satellites that are low on fuel or unresponsive, towing them to a...

Thank you, 3DDave. That is a good idea. I will try to reach out to them. The only reason I have not already is because large space companies are often difficult to get information from if you are not already a high value customer. Still, I will try.

Do you have a specific recommendation for a real website or service that would be better for this kind of question?

This is totally based. I completely agree.

I have already read this manual along with many others. The images in my initial post are from a few of them, as I stated. Also, the question was about LARs, not ESPA rings.

Well, I am not working with any singular launch vehicle, so there is no cart being put before any horse. The problem I have to solve is agnostic to launch vehicle selection. I also made it clear that I already know about payload user interface guides. That's where I got my pictures from, as I...

I'm really not sure why you decided to waste your time answering each question with basically, "I don't know." I'm going to assume your intentions were good, although FYI you did come off somewhat snide here and there. Here's a few things you should know: Dry lubricants exist and are commonly...
