[@mohameddrissi1075]

hello sir , i was looking for guide to select a thrust bearing but i can't find any one could help me with that ?

[@seetllee]

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]

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!

[@CampanadeGauss]

I have a question Why don't you calculate RAx?

[@ranjanpal7217]

Amazing explanation...Just one query..How can we know no. of balls in the bearing and their ball diameter?

[@TheBomPE]

Thanks! You would need to consult the detailed specifications provided by the manufacturer.

[@105andrex]

Thnk you so much for that good explanation!

[@TheBomPE]

I'm glad you liked it! Thanks for watching!

[@pisolo86]

Really love your teaching style, may I ask which book are you using for this class? Many thanks!

[@TheBomPE]

I use Shigley's Mechanical Engineering Design, 10th edition. Thanks for watching!

[@sinankunkut7257]

Why is not there a reaction force in the x direction at point A?

[@الكفراوي-ش1ن]

Please, I am from Egypt and have been searching for a long time for a ball bearing or something similar to install it for a handmade body that rotates at a speed of one million revolutions per minute without being subjected to corrosion or something that works with electromagnetism. Please, is it possible for me to find something like this? Thank you very much

[@Brissers]

Hi, thank you for this video it's been really helpful. You briefly mention at 3:40 that you "do not want more than one bearing carrying axial loads in a shaft". 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

[@Giuseppe_coachgius]

Thanks for sharing, what hardware/software was used for drawings? Was this prepared and then only the pointer was use to highlight the parts?

[@dejannikolic4647]

Do you have some books about bearings and other mechanical elements. Tanks in advance

[@joesaad3089]

just one question Sir , it seems that i can not find a clear video on KZbin which explains how to deal with a bearing subject to combined variable loading where this loading is changing according to a piece-wise function . Shigley's textbook only discusses variable radial loading. please can you help me . thanks in advance .

Correct.

[@prathedragon9847]

1:01:07 shouldn't Y be equal to 2.3?

[@Lloyd.B.]

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…

[@mohameddrissi1075]

hi sir , after doing calculations based on " only one of the bearing will carry thrust load" how can we make sure in real life that this specific bearing will take the hole thrust load and it will not be Distributed between both bearings

[@TheBomPE]

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!

[@rahulsarangi43]

16002 bearing in which 1 stands for what and what is difference between 6002 bearing and 16002

[@maherdaibes9344]

what is the name of the book ??

I teach this course out of Shigley's Mechanical Engineering Design, 10th edition. Thanks for watching!

[@bo-bx5hn]

Pinky Ring?? I thought that was only done here in Canada?

[@TheBomPE]

We have an organization down here in the States called the Order of the Engineer that was inspired by a similar Canadian group. I'm a member!

[@Fai9alsq]

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]

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!

[@alexreichart5592]

Is the reliability in this question supposed to be the reliability for the whole system or for each individual bearing?

[@TheBomPE]

I evaluated it per bearing. Thanks for watching!

[@taherbasrai]

Great video, but the magnitude of forces shown is too small for most practical application. Usually these forces are in thousands of pounds.

[@TheBomPE]

That depends on the application. Glad you liked it! Thanks for watching

[@vinayakkrishnaprasad358]

Metric system rules

[@TheBomPE]

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!
