Hi there,
my name is John Junior Lumbu (JJL)...currently living in South Africa.
With my engineering background, in this channel I will assist people to stay fit with their mind by first targeting people who love math, physics, CAD drawing, and related subjects; then I will invite each curious and open minded person to discover about basics of Mechanical engineering, technology, physical-metallurgy, science, mathematics and technology related topics. As I long to share with you above stated I will urge you to subscribe to my channel and also to click the bell button so that you might be notified every time I post something on this channel. We'll also share some sport events for entertainment' sake.
Salut mon nom est J.Junior Lumbu (JJL).

Mechanical testing or engineering tests are performed to determine various mechanical properties of materials such as strength, hardness, ductility, toughness, brittleness, etc. The precision results of these tests is utilised to determine suitability of materials for the field application. ...
charpy or impact testing is widely used to measure the toughness and ductility of the weld metal, base metal. Tensile testing of welds in place, with weld metal, HAZ, and base metal, allows an overall strength to be determined but usually cannot provide the strengths of the individual parts of the weldment.

Yes, true, those are camp steel steaks, you use them when you want to burn something in fire. Usually they don't need accurate machining
Ух классно длинные рукава когда нибудь точно их закрутит.Техн ка безопасности на высоте

Secvența cu o freză în timp ce așchiază nu spune nimic. Așa că lăsate de a mai face asemenea video.
Te înțeleg, totuși, deși nu îți place, altora le place. Acesta este un scurt videoclip. Vă invit să verificați videoclipul lung. Și sunt în engleză și franceză. Vă mulțumesc
@@JuniorJJLPhysicaMechanicaLumbu- Ca să motivez nemulțumirea mea trebuie să-ți spun că am profesat în meseria de frezor la o uzină de mașini unelte și agregate din capitala României timp de 51 de ani.
Înțeleg cu siguranță punctul tău de vedere în această privință, vreau să îți amintești că există oameni care încă trebuie să învețe, aussi un scurtmetraj este un teaser pentru a motiva oamenii să meargă să urmărească videoclipul lung pentru înțelegerea lor sau mai multă înțelegere. În general, apreciez sprijinul vostru chiar și pentru a-mi viziona conținutul. Îţi mulţumesc atât de mult 🙏🙏

вау, впечатляет 👌👌👍👍
I mis the engineering workshop with this videos. Brings back old memorie.

@@johanhenriksson6382 My pleasure
My first job was being a broach maker. Sharpener and surface grinder. That was a while ago.
Hopefully you enjoyed it.
Information video thank for sharing
Thank you Clarice, been a while
열심히 잘라서 훌륭한 모습으로 남아 지기를 바랍니다 사들 김종성
예, 좋은 상태를 유지할 것입니다. 과열을 방지할 수 있는 충분한 냉각수가 있습니다.

Хаааа, ты смешной 😅😅
Good job
Yeah, 👌
Merci Ingénieur pour ce rappel sur l'essai de Résilience .
Merci cher frère. Toujours un plaisir de te relire
Goodjob
For sure 👌
Nice
All I see is a guy who looks confused and is maybe not 100% sure what is going on?!
What you see there is a guy breaking standardized square bars called "Charpy samples". The purpose is to determine Toughness of the material where the samples came from, please watch these videos for explanation: ruclips.net/video/zAcFNjLs0TA/видео.html, ruclips.net/video/QK1LTk-3ZR0/видео.html & ruclips.net/video/F26jAhDM8ug/видео.html.

@@GreenHatPIrate Please either click the link of the related video or go through the channel. This is called short video.
It's a charpy v-notch tester. Pieces of metal are machined to a specific size with a notch and then (often) cooled to a specific temperature. The hammer falls and breaks the piece and then how far the hammer travels past the test piece tells you how much force was required to break the test piece. The ends of the broken pieces are then examined to determine how much of the fracture is from "breaking" or shearing to determine how ductile/brittle the material is. It's destructive testing used to determine material properties of a larger batch or piece.
60 was the result of the test. I'm guessing 60 joules.
@@Randald Thank you for explaining, 🙏🙏
@@Randald Yes, on that specific test piece, the result of the absorbed chock energy is 60 joules.
