Hello! I am a college professor who has decided to put some content onto RU-vid. On my channel you can find playlists about Machine Design (I use Shigley), Measurements, 3D Printing, and a few other topics. I have also begun creating shorter videos that give a one minute overview of a single topic. Overall, most of my videos have to do with mechanical engineering in one way or another.
I try to respond to comments as much as possible so feel free to leave a comment.
I usually post at least one new video a week so subscribe to keep up with the series.
I am planning a new series of videos for this summer that may not be quite as technical as some of the videos that I have out right now, but it should be fun!
Thank you for the video! Please, correct me if I'm wrong. 40:55, joint separation is possible for External load = Initial preload only if we assume that members have infinite stiffness. In reality external load is bigger as per bolted joint diagram.
Good question. The term Additive Manufacturing is used as a reference to the more traditional Subtractive Manufacturing (things like milling, cutting, lathing, . . .). Personally, I have started using Additive Fabrication for 3D Printing as most of what I personally do is not something I would consider as “manufacturing”. I don’t think there is a strong reason not to use “3D Printing” as a term though.
@@KellyBC Absolutely. I would even say it is a must. And you need proper ventilation for the stuff to not linger and still get everywhere . That´s the only reason I don´t do resin printing. I don´t have a separate room and I am not willing to pay for one just for the resin printing. All those advances in this tech and yet nobody solved that problem.
I made a mistake in this video - I was using the Ender 3 (2018) config file which is not going to work with this printer. I realised that just a few minutes after logging off. We will pick up on Friday with the correct file and carry on with our Klipper install. All of the steps in the video are correct, just for the wrong printer. :/
That is very possible. I don't recall exactly what I was doing there, so there could be some error in the final result. The process should be valid though - just maybe not the "answer". Thanks!
Nice video,Excellent explanations. I have a question: I don't understand how the safety factor calculated by SOLIDWORKS should be interpreted? Only with the preload I have a coefficient of 1.3. It is therefore impossible to have a safety factor of 2 given the preload. So when do I reach the yield point? the answer is: when the coefficient calculated by SW is 1, Right?
Thanks for Sharing Kelly - sorry just seeing this now, but glad you had fun and made a great video! I'll be sharing it with the community and listing it on the web site soon :) Happy Recreating!
Your videos are very useful for the machine elements course in mechanical engineering. Also, it is very successful that you visualize theoretical topics with tools. Sometimes it's hard to understand just from the picture. Thanks really.
hi! thanks for the explanation but in fact, when we have the two values of K, one K for the srew and the bolt and the second for the structure set, how do you manage to use the values in a concret design. i'm just curious to include the full calculation in a project to avoid differents mistakes, havre a good day.
Please make video example for pipeline simulations Calculations: pipeline route study, wall thickness and material grade selection both rigid and flexible pipe, collapse and buckling analysis, on bottom stability analysis, pipeline end expansion, pipeline free span, bottom roughness analysis, lateral bucking analysis, pipeline crossing and its structural supports design, fatigue analysis.
I don’t currently have notes for these lectures. I am teaching the course again this quarter and will see if I can simultaneously add some notes to these videos.
I didn’t have much trouble on an Ender 3. I did have a larger diameter nozzle (0.6mm) and the print bed turned up to around 80C. Also, the layer cooling was set to 50%.
Nice! I was thinking of buying burnt titanium chameleon filament, and I needed to see what it looked like first. It looks amazing! 🤩 ❤❤❤ will definitely buy
I am interested when watch you , I wish you continue to explain Examples in real life, such as machines applied in real life, why choose the pulley or so-and-so or the methods of manufacturing each product and then look at the design of the machine parts.
I hope you will have a udemy course that is dedicated to understandingo Shigleys book.This is quality and udemy material.The effort is worthy of a paid content.
your channel popped out at my home feed .This is after giving up finding a intuitive channel that will explain basic concepts and mechanical parts in Shigleys books.The diagram are very challenging to analyze if you dont know how to imagine the real part in real life.Thank you!. 4 years of hunting ! I hope you continue.Looks like you have every chapter discussed in shigley.
If you image the welded part pulling away from the wall when loaded it is bending. If you imagine the welded part sliding along the surface that it is welded to then that is torsion/shear. I hope that helps some.
@KellyBC I din't get it. The scenario here is quite different. Someone tells the concept of centroids, and someone tells the concept axis to check whether to go towards torsion or bending. The recognition of bending and torsion with the help of geometry isn't taught here. Please make a live webinar on this topic. We all students will be very thankful to you for that.
That is a really large part and most consumer printers are not going to have that sort of build area. I have not tried it personally, but there is a new (still in Kickstarter) Elegoo Orange Storm Giga. You could also try to break the print into smaller pieces and weld/glue them together. I only have one printer that could do that in a single print and it is an Erectorbot. There is a big Tronxy printer that is out there ($3000 or so) but I haven't seen one in person. Personally, I would try to break the single part into smaller parts and print them.
It depends on your budget, but in general yes. Today there are Black Friday deals that have the base Ender 3 for $99 which is an incredible deal to get started with 3D printing. Printing a mask on a “bed slinger” like the Ender 3 can be tricky since you end up moving a lot of mass near the end of the print. Masks do work better on printers where the bed does not move forward and back, but instead moves up and down. But in general, those printers are going to be many times more expensive. I know that isn’t a clear answer, but maybe it gives you some terms to search for and investigate. If I had more money to spend on the printer and wanted to print cosplay items, I would go with one of the Bambulab printers. They are on sale now as well. -November 2023.
