You state that you covered this previously in more detail, what chapter in Shigley mentions this? Also, did you make a video of yourself covering this in greater detail? Thank you

This channel is just amazing. Are these from classes at any University? If so, which one? I'm using your videos to study for my Machine Element Design final exam, but i intend to keep studying for my own the other subjects you teach, mainly dynamics. Your classes are just the best! I hope this channel grows. Im sharing it with my friends already. I'm from Brazil! I have to say smth: when i search "TheBom Bearings" your video just doesnt show up! Its really hard to find you by just searching the title of the subject one wants to learn. You maybe will want check it out for your own good and your channel's.

@TheBomPE 5 жыл бұрын

You are very kind! Yes, most of my videos are captured from live lectures I give at Louisiana Tech University (the channel name comes from my name: Dr. Michael Swanbom, PE). I'm sorry it is difficult to find my lectures with search terms. I could probably improve that to some degree if I went through and added good video descriptions on the ones that lack them. I know that would be good to do, but I have found it difficult to prioritize that over my other responsibilities and interests. I don't have any staff :) Beyond improving descriptions, I would love advice about channel promotion from anyone who knows something about it that I don't (and I wouldn't say I know that much about it). So far this channel has been very much a side hustle, so I'm probably mostly interested in ideas that don't take too much investment of time or $. Word-of-mouth (or word-of-online-forum) is the best form of promotion in my book. Thanks for the positive review, and for spreading the word to your friends! I'm glad you find it helpful! I'm going to try to capture two more courses worth of lectures this coming academic year (ENGR220: Statics/Mech of Materials and MEEN371: Dynamic Systems) so stay tuned!

I’m thinking about building a small wind spinner. Does anyone have any idea if there are bearings in existence that are really small and able to work no matter which direction force is applied to them?.. I’m looking for something about 3mm wide, up to 2cm long, ideally tubular, or some such... I discovered fishing swivels yesterday, but I don't know if they would spin freely when being pushed, as opposed to pulled (as they are designed for)… I suspect they might not spin freely enough anyway. Some are named "Column type rotary ring bearing swivel" that seem close to what I want. Maybe I need to make a bearing type thing out of tubing and rods; but it would probably be easier if something exists already I could just plug in and use…

15:30 why we don't combine the y and z directions and call them radial direction and the x is named axial direction?

@TheBomPE 4 жыл бұрын

You can, however, the "couple" dealt with at about 21:30 will be applied around an axis parallel with the y. So even if you constructed a "radial" axis, it may not be obvious at the outset what direction "radial" actually is for the bearings once the couple is considered. I thought it would be more clear and about the same amount of effort to present it as I did. Thanks for watching!

The shaft would be designed so that a shoulder or snap ring would only be placed at one bearing, not both. That way the shaft will be free to slide axially in the other bearing. Thanks for watching!

@TheBomPE 4 жыл бұрын

Yes, it is certainly clean. So clean that you aren't forced to think about it much while you are learning. It is an advantage of learning engineering in the US that students have to deal with 2 units systems. It forces some level of denaturalization from unit systems entirely, and opens the opportunity to understand metrology more fundamentally. That is one reason why I choose to include problems from both systems in my content. Thanks for watching!
