Machine Design Lectures on YouTube (based on Shigley)

Thank you for posting these. I and others at CR4 (who typically are not very active online during weekends) will enjoy looking at these.

CR4 has a "not a homework cheat site" policy and I think that it sometimes hurts us by going too far. Your videos and the many other videos on YouTube (not the cat ones) are a resource I could have not even dreamed of when I was going through school. We should be sharing useful links and helping students learn or relearn. This includes both current students and those of us that haven't had to turn in a homework assignment for a few decades.

I don't have a good, clean list of educational videos that I like but in addition to yours I'll list a few of my favorites below. In my opinion it would be good if CR4 had some sort of "groups", "sections" or "chat rooms" set up where students that are willing to do their own work can be helped, videos such as yours are linked and video creators such as yourself are encouraged to drop by and participate from time to time.

Some of my favorites are:

https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw 3blue1brown, lots of good physics videos

https://www.youtube.com/channel/UCiEHVhv0SBMpP75JbzJShqw Walter Lewin, former MIT professor, physics book author and great physics professor

https://www.youtube.com/results?search_query=matt+anderson+physics Matt Anderson, great physics professor

https://www.youtube.com/results?search_query=greg+durgin Greg Durgin, a great Georgia Tech professor.

https://www.youtube.com/user/diggitydev Doc Schuster, a high school physics teacher with many short, high energy videos targeting specific topics.

https://www.youtube.com/channel/UC640y4UvDAlya_WOj5U4pfA NPTEL India, the educational system in India is very serious about producing videos for distance learning and they are generous in providing that content to all of us.

https://www.youtube.com/results?search_query=r.+k.+shevgaonkar Transmission Lines and other courses taught by Professor R. K. Shevgaonkar are very good.

https://www.youtube.com/user/subcooledheatpump User subcooledheatpump created a number of very nice videos on electronics. The son of the owner of Dave's Heating and Air Conditioning in Mansfield, Ohio started learning about electronic controls for air conditions and kept right on going. He has made numerous educational videos showing his experiments and projects.

(Note to CR4 Admins, a "chat room" like this could gain momentum since video creaters who participate could indirectly get YouTube revenue and book sales and people starting a educational career could get resume credentials by being a xxxx count student interaction tutor on CR4. It would also give Lyn something to do when he is not laying a fossil sidewalk between his driveway and that bench in his front yard.)

I think such services are at least borderline fraudulent, along with the "students" that use them. I would never knowingly hire any such persons.

In contrast, the OP's suggestion is commendable.

Students learning how to do things for themselves is important, and that is my vision for the videos I post. For-fee services that circumvent the learning experiences envisioned by earnest educators are not in line with my vision regarding what is best for students.

As a ~14-year member of engineering faculty, I often place statements in my syllabi informing students that services such as these are not permitted. Students that violate syllabus policies to use paper-writing or homework-completion services are desensitizing themselves to unethical behavior. This damages them as effective servants of society (as engineers should be), and this in turn damages the engineering profession, even for its ethical members.
