PHYSICS OF LEVERAGE & HISTORY OF MECHANICAL DEVELOPMENT SHELL OIL FILM MD61394

[@Carstuff111]

I love these films!!! Thank you to the folks uploading these, because you help this nerd find something great to watch! These may be considered by many to be outdated, but the information contained is STILL relevant today!

[@stevepape9011]

I am with you.

[@ejones6647]

This is very informative and very insightful!

[@wolfgaming1274]

They should make these types of videos mandatory for highschool its history math physics and pretty much everything rolled into one 👍

[@paddlefaster]

They used too.

[@MarioMastar]

In science classes you'd see videos like this, they just are more generalized and have less aggrandizing (the whole "Crowbar, aiding man since the beginning of worded history" and their emphasis of "HIS" mostly being dropped in favor of getting to the point). But you're right, seeing the evolution of these concepts better explain how we went from cutting wood and fetching water with pails to industrial machines that literally do the same thing on a smaller, faster and more efficient scale multiplying it's output. But also in an apocalypse where we had to start over, we can imagine how we'd get back to modern technology fairly quickly

[@mitchelldakelman7006]

We showed this film in 8th grade science in 1967, but not too long afterwards it was withdrawn. It was eventually updated with a newer color version which we can post in the future. The animated sequences in this film were reproduced in the new version.

[@roger72715]

Extremely grateful for these brilliantly explained free videos

[@mitchdakelman4470]

We showed this film in our 8th grade science class in 1966 since the film dealt with physics and I had not seen it until then. In 1967 Shell withdrew all their older black & white films frim their lending library but still made the film available by giving copies away for the asking. And in 1974 I called Shell and they still had one, and thats the copy you are seeing!

[@TheCymbalProject]

Can we all take a second to appreciate the quality of the animations in this film.... friggin amazing work

[@jamesslick4790]

11:58 - 13:15 was an elegant explanation of WHY gear teeth are shaped that way! 👍👍

The men that designed and engineered these gears were pure genius.

[@50centgotshot9times]

yeah they were...or..... aliens

[@markmilam3152]

The people that made the machines that made the gears are geniuses like Gleason Tool Works.

[@jamesdonovan5165]

Yes they were. The person that put the stopwatch in the film, not so much.

[@backho12]

[@rolandjohansson7428]

This is how documentaries should be made. No pointless and annoying background music, as is so commonplace today.

[@mitchdakelman4470]

The early Shell productions used "live" background sound, but the later ones used original musical scores composed for the film. Look at Song of the Clouds, a production that Shell did in 1957, and The Drama of Metal Forming, made in 1959, uses both live sound and music at certain points in the film.

[@publicmail2]

A was laughing watching these because it was so visually informative, I couldn't believe it, especially on the cycloid. The Shell oil video are the best, see the one on metal forming in color.

[@mitchdakelman4470]

This film was one of many made by the Shell Film Unit. This one was produced in 1939, and has an American narrator, Harlow Wilcox. The British versions would have a British narrator. I think this is a great production for its time. We showed it in 8th grade science in 1967. The Shell Oil Company withdrew all their old black and white films in 1968 and gave them away just for the asking, so many teachers who liked the film could have their own print for good.

Another pure gold video! Love the simple explanation to some complex issues.

[@jockellis]

This morning I was cleaning the rust protection off a herringbone gear - mentioned at 17 minutes prior to crack checking it and was wondering about the history of gears. Then when break came I got on KZbin and this was near the top.

[@MarioMastar]

Seeing the evolution of technology really puts into perspective how a civilization who lost it all could build back a modern Metropolis like we have today in a matter of years. I'm even seeing regular people build their whole house from the ground up by themselves now thanks to understanding the fundamentals and efficiency.

[@jockellis]

What he calls the worm gear is actually the worm. It turns a worm gear of larger size and softer material. If the worm is steel the most common worm gear is made of brass or sometimes cast iron. If the worm is of brass as it is in so many model trains the worm gear will be of nylon or another plastic.

Just curious are you familiar with Jeff Quitney? Loved his work shame his account got terminated.

[@roger72715]

Yup... I searched it for a long time. Sad that its gone

[@PeriscopeFilm]

The problem with Jeff's channel was, all the films he placed on it were poached from other sources. For example, he stole dozens and dozens of films from our channel, blew them up to hide our identifying marks, and then re-posted them claiming they were "restored" and "enhanced" when in reality they were badly damaged, distorted, and re-positioned. He was doing this with videos from dozens of museums, libraries, and the government. Whereas we spend enormous time and energy to preserve motion picture history, all he did was take things that he felt were up for grabs (some might call it stealing but we're not going to go there). We suspect this is the reason his channel isn't around any longer.

TOO MANY ADS ON THIS VIDEO!

[@mitchdakelman4470]

The ads are added by KZbin. The actual film print, acquired from Shell in 1974, has no commercials! And when projected on the 16mm projector, its quite remarkable in its picture quality! All I did was called the Shell Film Library, and you are seeing what was sent!

[@joegoldman3065]

I find music in these Periscope films fascinating to me it perfectly conveys an age in American history when America knew I could beat the living shit out of any country economically technologically or any other respect that also seems to convey an age of infinite racism and thusly notion that everything was going great all the time and that everyone was happy

[@I_leave_mean_comments]

That time stamp is literally RIGHT in the middle of several scenes. Please make something transparent or off to the side or something. Like I said before, I understand that you're uploading all these videos, and you want to make sure no one steals them... but that timestamp is far too big. It's going to end up hurting your channel in the end, because as this channel becomes more popular, people will see how annoying it is, and upload their own old documentaries and videos without that massive annoying timestamp.

[@mitchdakelman4470]

The time stamp discourages others from downloading and selling copies at the expense of the exhibitor who has paid to have the film repaired, cleaned and transferred and the film's actual owner who has put time into the film's maintenance and repair. I'm a but spoiled, I obtained a retired print from Shell Oil in 1974. They still had some copies left, but were no longer loaning it out.

[@bane_37]

I leave mean comments, These videos are all in the public domain. Free. To anyone. These guys go and get the videos and convert them into higher definition and then sell them. And because they are in the public domain it isn't illegal. You can find all these videos and more via archive.org or find Jeff Quitney on Vimeo. He uploads the same videos (and more) with no watermarks on them.

[@PeriscopeFilm]

Here's the issue: Here's the issue: Tens of thousands of films similar to this one have been lost forever -- destroyed -- and many others are at risk. Our company preserves these precious bits of history one film at a time. How do we afford to do that? By selling them as stock footage to documentary filmmakers and broadcasters. If we did not have a counter, we could not afford to post films like these online, and no films would be preserved. It's that simple. So we ask you to bear with the watermark and timecodes. In the past we tried many different systems including placing our timer at the bottom corner of our videos. What happened? Unscrupulous KZbin users downloaded our vids, blew them up so the timer was not visible, and re-posted them as their own content! We had to use content control to have the videos removed and shut down these channels. It's hard enough work preserving these films and posting them, without having to spend precious time dealing with policing thievery -- and not what we devoted ourselves to do.
