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).
Cette chaine vous amene les fondamentaux sur l'ingénierie mécanique, technologie, métallurgie physique, science, mathematique et sujets reliés à la technologie.
Un peu de loisir pour bien digerer...

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.
