Bad presentation altogether.

Your blackboard is not visible. Wrong angle and distance.

The Hall effect is a lot more than academia states.

making a lecture with masks on is so disrespectful for the audience.

It's a bummer you had to use inappropriate language. Otherwise I thought this was an excellent video.

why does my structure move away from the fixtures?

Hello, congratulations on your work, it is very interesting. I would like to know were the Cougs In Space wiki link is. Thank you!!!!!!!!!!!!!!!

38:00 I am sorry but this mesh is total shit. We used to mesh therse things like an artist (on hypermesh though), solidworks sucks at this or you need to get in control of it. Triangle elements increase stiffness so you will find more stress than you should and it will bring more singularity risks. Thanks for the great video btw.

Sir how are very low thrust it provide velocity to satellite

My guess would be that the positive ion would quickly capture a electron again, because electrons are much more mobile and are attracted to the ion quickly, it will either neutralize it or knock of electrons again, while the ion is still positive it can accelerate in the electric field. But I guess those ions who finally exit at the end are all neutralized. Or it works completely different.

A bungled and unnecessary 44 mins video. Enthusiasm is a virtue but must be tempered with knowledge and discipline or it results in what we see here. Perhaps you could make a video when you have understood what you think is worth conveying but please make it less ME, ME, ME.

It circulates because the electron is smeared out in space, more so in areas where its momentum can be more precisely observed. Around these locations with some probability the electron tunnels either left or right and the average motion of these electrons (the current) is visualized by the green dot. 🥂

How do you get the values which you are entering in frequency curve?

are you using filament as a neutralizer cathode?

Hi! I've been working on a hall effect thruster in the industry for 3 years now and this was very helpful for me to get all the concepts explained in one place. Thank you and love the enthusiasm.

What's a frequency curve

Ahh league of legends 😌

Sir could you please provide geometry file @cougsinspace

Would it be possible for you to create a video that does a thermal analysis of a cubesat in space? It would be extremely helpful for my design team! Thank you

Hey guys thank you for doing this! I'm a structure lead for a Cubesat team in Sacramento trying to build our own CubeSats and this helps!

Thank you guys for this video! Currently I'm part of a small team in Sacramento developing our very first CubeSat

Hey Colin, really nice work trying and make this very interesting topic accessible. I especially appreciate it since I am working on a project paper leading up to a master thesis about hall thrusters so I guess my knowledge level is kind of like yours. I think part of the open question about the acceleration of the ions is the electric field created between the anode and the space charge of the circulating electrons. This is why it is critical to limit their movement to the anode, which is done by good magnetic field design. The video is only a couple months old, so if you still read the comments we could also exchange some more about it. I'd love to! Cheers! Fabian

Thank you for this video and source, keep sharing!

This has been very helpful to me! Currently doing my graduation internship where I need to design brackets that will hold a small moon rover in place during vibration testing. Thanks so much!

At 41:16 you said that with 3sigma you have a 95% probability but in fact, 3sigma corresponds to 99,7% of probability. Just a litte correction. For those who don't know, he's talking about the normal distribution (en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule).

hey, would also love if you could do it for the 6U Cubesat

Hi, dear friend, do you have the cubesat design file to test on my computer? Thanks

can you share your E-mail id?

thanks !!

this is so helpful, thanks

Who works in solidworks with a less than full screen?

Can you train me how to make it privetly ( personaly )

Great discussion. Thanks for the video.
