Ohhh I think I'm getting it now- there are two multiplication factors I was missing: one is the 2x multiplication of the mirror's angle; and other is the lens focal length thing. Before I watched this vid I was imagining the only principal at play for getting precision angle measurements was the distance from the mirror to the scope (similar to how you could stick a laser pointer on the mirror sled and project its dot into a wall at a great distance to get a fairly precise measurement of a small angle).

Long slog, but great clarity. Thanks.

How do I make it a blue gem?

Awesome info!!

Excellent tutorial!! Great explanation and graphics.

It's ashamed that high quality content on KZbin gets so little views and subscriber, while stupid contents get lots of views and subscriber.

We definitely learned something. Thanks for the video!!

i watched this video today and i find its very helpful for Mechanical technicians and supervisor to maitain them and also for interview questions mostly asked by the interviewer💯

Nice explanation working of positive displacement pump with animation, thanks for sharing

Nice presentation on compression packing for rotating equipment, with actual equipment in the field, that makes presentation more effective and knowledge enhancing. Thanks for sharing information.

Really thanks! you did a great job.

I heard them called beam gauges.

This video is excellent!

For trihedral socket, you can use 3 ball-bearing on round socket. It works very well 👌

Thank you so much, I will suggest my students to watch your video.

I have to do a talk on the pump on centrifugal pump at out fire station. This helps. Thanks for that.

How long does it take for the oven to reach that temperature?

What is the porosity of graphite

Woww!! Thanks a Tonnnn 😍😍, Found it veryy Useful!!

Marvellous, it's a really good video for refreshing the concept of centrifugal pump ... The explanation is clear and concise. Way to go, Laney

Ah, dude, If I only had this video 5-6 years ago when I did my first (home) anodization, it would save me few months of research. You put literally everything in just 30min. Bravo

I am pretty certain my brain just exploded🤯🤣🤣 great stuff as always Adam.

I wish you can you make more videos on mechanical equipment! More than willing to pay for such high quality educational content.

So, does the liquid transport use kinetic energy or pressure energy?

The draft is so cryptic. Why dimensions are so tiny and what is Aluminum?

What a nice content

The world needs to learn more of this. Thank you!

So good!

your fingers are were shitty 😁😁😁

your fingers are were shitty 😁😁😁

Excellent presentation. I understood it all

Brilliant use of your little optical demonstration kit very clever. Excellent excellent description and video of a process it's hard for most people to imagine keep up the good work

Thank you so much brother, this will also help in interview

Video was very helpful.

Just make sure it’s aligned good

Nice video and an excellent explanation.

Amazing! Thank you!

Where's the link to the build?

This was a great intuitive explanation nice!

A pump doesnt create pressure. Pressure is created from a resistance to flow.

Very clear !! 👍

Oh yea? I plunge with endmills.

I've watched this video multiple times already.

4:33 that a partial differential equation, linearity is not an issue since you are trying to solve for a specific use case (I.E. given sizes and weights, how high will it float with a given air pressure). With a bit of work, anyone with some PDE and R programming should be able to find an approximate solution. Anyway, I am pretty sure Gelbert just drilled holes in his granite and turned up the pressure until it worked - he is far to practical a person to spend time making plans when he will still have to spend hours tweaking.

Where did this series go?

Saw the hat; we used to do that at my previous job for holes in flat surfaces at 45 degrees. Drill bits would skate off but mill bits worked. Pretty expensive way to make holes in general though, since the materials, espeicially the zinc and copper, rapidly dulled the bit.

This video made my wife divorce me then my kids started to hate me for trying to teach them this.

I needed this mini-lecture for so long. The BEST explanation of the physics of a centrigufal pump!

great detail

1) Adding an acid to a water you're not avoiding the exothermic reaction itself. You're avoiding formation of shallow layer of water on top of the acid. Such a disposition concentrates all the heat excretion near the surface and it will cause boiling of water layer and sputtering highly acidic solution all around. It is actually not enough to just pour an acid into a water -- you also need an active mixing of the liquids to spread the heat evenly. And even then you need to carefully control whether it about to boil. 2) No way you can get any violent reaction, any significant heat from the 30% sulfuric acid with water. It's too diluted. So you better won't be fooled by the calmnes of that mixture when you'll be dealing with some really highly concentrated acids (50 and more % for sulfuric acid) and especially oleum wich is pure evil. ____________________ It's better to have 2 or 4 smaller cathodes spreaded evenly around the edge of the vessel than one at one side. As far as the largest current goes through the least resistance, the surface of the part will be processed unevenly having just one cathode without rotating over time. Especially if it has any complex form.
