Stress and strain is one of the first things you will cover in engineering. It is the most fundamental part of material science and it's important you understand some of these ideas going forward.

The second channel fell through. I need a university to sponsor that channel and provide the course materials, I was hoping to just do the animation and narration. Still hopeful it will happen further down the line, but for now I just don't have enough time.

This video is super fast, hopefully you got a basic idea of material properties. I wanted to create a second channel where I can explain things slowly and in detail for the people who want that kind of content. I am hoping to partner with a university and release proper college grade education on that channel. The link is in the description. Thanks guys. Really appreciate your support.

I am just a guy who likes to spend his free time on KZfaq, dicking around watching videos over space exploration and a few outlandish scientific concepts. I already have a hard time figuring out what to do with my life, and I'm currently doing an exchange year in Germany wondering what to study in college(or even study straight away at all ). Finding your videos in my reccommeded list has really sparked an intrest for me in material science, a branch of science I've never really bothered to think to much about before, yet also made it clear to me that I would live to study some form of physics. It's so hard to be in a classroom thinking about when the subject material will be relevant, or staring at marvels of the world without understanding what intellectual work went into it (let alone understanding the work in the first place). So, thank you. And please, after watching your latest video on the power grid, keep up the good work

Biggest confusion in material science about stress-strain related stuffs, is that whether it should be considered under "mechanical" properties or not. In reality it's basic to thermal, electrical, magnetic, optical and acoustic properties as well. Because the nature of external force can be anything. eg. electric potential difference/voltage applied on the material can also cause strain and thus stress, which are actually internal reaction forces to the external action forces. Ironically, internal reaction of a material, ie the stress is fundamentally of electromagnetic type.

@@RealEngineering THE UNIVERSAL, SIMPLE, CLEAR, AND TOP DOWN MATHEMATICAL PROOF THAT E=MC2 IS F=MA (ON BALANCE): It is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. NOW, carefully consider what is THE MAN who is standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=MC2 IS F=ma. Very carefully consider what is BALANCED BODILY/VISUAL EXPERIENCE. (LOOK up at what is the blue sky, AS THE EARTH is ALSO BLUE.) Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. Great. It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. E=MC2 IS CLEARLY F=ma ON BALANCE. Objects AND MEN fall at the SAME RATE (neglecting air resistance, of course), AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The rotation of WHAT IS THE MOON matches it's revolution, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Consider what is THE EYE. So, LOOK at what is the fully illuminated (and setting) Moon AND the orange Sun ON BALANCE. Now, think about what is LAVA. E=MC2 IS F=ma. SO, we then multiply ONE HALF times one half in order to determine the size of the Moon. (It IS about one fourth the size of the Earth.) This is CONSISTENT with the fact that the Moon IS (on balance) LAND. Therefore, the density of THE SUN is (ON BALANCE) about ONE FOURTH of that of what is THE EARTH; AS E=MC2 IS then CLEARLY proven to be F=ma; AS ELECTROMAGNETISM/energy is gravity. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Again, it all CLEARLY makes perfect sense ON BALANCE !!! The BULK DENSITY of the Moon is comparable to that of (volcanic) basaltic LAVAS on the Earth. The energy density of LAVA IS about THREE TIMES that of water. SO, now, get a good and CLEAR LOOK at what is the ORANGE SUN !!! We WOULD then multiply ONE THIRD times one half in order to obtain the surface gravity that is experienced by the man on the Moon. (It IS one sixth of that of the man who is on the Earth.) The maria ("lunar seas") on the Moon do take up ONE THIRD of what is the near side of the Moon. Excellent. The Moon is ALSO BLUE on balance. Great !!! Now, in conclusion, the land surface area of THE EARTH is 29 PERCENT; AND this is EXACTLY ON BALANCE WITH BOTH one third AND one fourth; AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS CLEARLY AND NECESSARILY F=ma !!!!! GOT IT !!! GREAT. E=MC2 IS CLEARLY F=ma ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY proven to be gravity ON BALANCE. Gravity IS ELECTROMAGNETISM/energy. It must be, and it is. By Frank DiMeglio

I've watched this video probably 2 or 4 times since it was released. But I still have to come back to it every so often because I keep forgetting what the different material properties are and what they mean. I guess it's one of those things where I don't use it a lot day to day, so I just naturally forget it over time. Like how I had to teach myself long division about 6 times before I finally stopped forgetting. Because who long divides these days? I only needed to use it because I set myself the task of finding a square root of a number by hand. Otherwise I wouldn't have even needed it. Nor have I since, that I can recall.
