THE INTERNET IS NOW A HUMAN RIGHT INTERNATIONALLY

Fantastic.. retired electronics technician

GD&T isn’t right for everyone. A lot of industries use supply chains that are unfamiliar with the ASME or ISO standard and it can quickly result in confusion and increased cost. Dimensional tolerances are appropriate for many parts. Modern technology allows for overall tolerance and basic dimensioning to be inspected by optical comparators against the 3D geometry.

Nonsense. Bernoulli applies to fluid flowing though a pipe of varying circumferences along its length. It does not apply to sails or wings. A sailboat's sail has exactly the same lenght on each side, but still produces lift. Many sailboats also have a hydofoil that is composed of a flat 1/4 inch metal plate. This foil also produces a lift vector which is necessary for a sailboat to sail upwind.

This video reminded me of my first internship where I got to built a cubesat and really provides a basic overview about the main things about satellites. However, I would like to add one thing at 12:12 . When reaction wheels reach their saturation, it does not mean they cannot be used anymore. If they are played in a coil, their rotational energy can be converted into electrical energy which will slow the reaction wheels down, while also providing power to the satellite.

It's not so much that the air is glowing faster, it is the effect of the faster flow on the physical properties of the air at that time. The air molecules flowing over the wing have to spread out to reach the trailing edge at the same time as the air molecules flowing under the wing. Fewer molecules per square inch exerts less pressure per square inch. So during the time the wing is in contact with that "piece" of air there is greater pressure below than above. Faster moving air , more pressure/time, more "lift". A Cessna wing generated enough lift to fly the plane at 40mph, a Boeing 747, more like 160mph Big wings, fast speed, more lift force.

Veryyy helpful! Especially when I have a Thermal Eng. exam in a couple of days. Thank you so much for these insightful videos.

Yall glaze tgis channel too hard, this is the most unnecessarily complex explanation of fem ive ever come across

I didn't skip any advertisement in your videos, you deserve it man!!! amazing quality, straight to the point and very easy to understand engineering video. keep it up 👏👏👏

so my Tresca stress calculation should give a higher stress for the same state as Von Mises?

Really cheap... now they're $3 per bolt setup minimum. BBB

Mindblowing stuff! I just got my first CAD job, coming from an art and CS background, and this will help me look at the the assemblies in a whole new way!

As CubeSat designer, this is a breeze to watch. Kudos for the details and getting all the animation details right including terminology, units and order of magnitude for numbers. Watched it on Nebula but they don't do comments so here it goes!

Was very practical , understandable and complete information . Thanks a lot 🙏

Something that has been confusing me for a long while, is the relationship between ductility and toughness. As far as I understand, ductility is a measure of the ability to plastically deform. I also understand that the plastic deformation is the main way that energy is absorbed by the material before fracture. This leads me to believe that materials with high ductility must have high toughness and vice versa, since toughness is the ability to absorb energy before fracture. However, i have seen some things online claiming that high ductility and high toughness do not always go together, and that even some ceramics are tough even though they are not ductile. Can someone please explain this to me? Like how can some ceramics be tough but then not plastically deform? How is the energy being absorbed in this “tough” ceramic? Are toughness and ductility not directly proportional? I need this info for university, would be really grateful for help. Incase anyone reading this is a German speaker, I have a further confusion, that I would love help with. As far as I understand, the translation for the German word ‘zähe’ is ‘tough’ and the translation for ‘duktil’ is ‘ductile’. In german ‘zähe’ seems to be used interchangeably for ‘duktil’, which in english would mean that toughness = ductility. But I can’t believe this is true. We can clearly see that ductility and toughness have different quantitative values. Are the terms used liberally in German? Was ist der Unterschied zwischen zähe und duktil? Bedeuten sie das gleiche auf deutsch? Was ist dann toughness auf Deutsch? Hilfe!

Anyone also here to learn the basics of engineering to draw mechas?

good effort

great videos, which program do you use to create those animations if i may ask?

Wonderful Video! Thanks a Lot

She torque on my wrench till I preload with nut force.

The nut factor 😅😅😂😂😂

idk man, i just watched a Neil deGrasse Tyson video and he said the flaps go the opposite way during takeoff, and he's very knowledgeable on the subject of aviation 🤔🤔

POV had a class for this, why couldn’t this video come out last semester 😭😭

this might be the best video I saw so far on KZfaq!

Excellent work 🥵👍🏽 thank you to the team ❤️

This is the biggest video yet, super impressed by everything here.

Thank you very much. This video was extremely helpful ❤

I am sure that the satellite that are shown in your video is old technology it were used at 50 's or 70's .

buenisimo

Great videos! You explain very clearly and in simple terms engineering theories. So much better than expensive university courses.

Method of joints, method of sections, force pologon.....several ways to design or check a computer run. Secondary stresses easily checked for added bending tension or comp. between panel points (truss joints).

As a Satellite Systems Engineer myself, I can confirm this is the best explaination one can have in 27 mins. KUDOS.

Thank you for this masterpiece.

Tks a lot for this vid, love u.

I work in the aerospace industry, and these models and animations are quite close to real components. Great job. Should've included phase array antenna for transmission system. They are amazing ..

how to decrease the pressure with constant velocity of water flow in water pipeline..? Is it possible to decrease the pressure without variation of velocity..?

I would like to know the derivation of the equation VQ/IT. I am happy to just plug the values in but im really interested why the equation is setup in such a way. thank and your content is amazing

This might be the most concise explanation of satellite design I've ever seen. I would like to add this to my "new hire guide" for employees who come help me build satellites.

The sound at 15:10 was so nice

Excellent video! Thank you for your time and effort. Bravo!

A perfect video.

Typical "explanation " for those who understand already everything . By the way: I didn't expect Paid-like comments here.😶

Finally somebody that got this shit right

"articulated solar arrays" -- how does that affect the attitude/orientation of the satellite? if the solar panels change position, that must have an effect on the satellite right? because if velocity is constant and it's at orbital velocity, there's nothing except that mass of the satellite for the motors orienting the panels to react against? i think?! i'd never thought about this till the video mentioned it

Precision and quality of video is outstanding its similar to actual thing

This is honestly one of the best videos ive ever seen

Thanks, this video was very helpful for building my own Fractional Orbital Bombardment System.

Never seen this kinda of video before. ❤❤❤ You from Pakistan
