How to make a waterproof box from sheet metal
You don't need to weld the sides to get a waterproof box you just need to fold the sides

How to make a sheet metal break
มุมมอง 6004 หลายเดือนก่อน
To make boxes with high walls you need electromagnetic sheet metal break, these cost a fortune. But you can make one from scrap metal that can handle high-walled boxes.
Simple way to calculate the strength of wooden beams
มุมมอง 369ปีที่แล้ว
If you have a tall wooden support beam, and you want to replace it with a wider one, with the same strength, this calculation is very simple. The scale used in the experiment reads in metric tonnes.
will cotton fall in the same speed as steel in vacuum?

There are many videos dealing with this topic. And hopefully most people know the answer. But since I got such a good video with a cheap high-speed camera, I post the video

If you want both wheels to be lifted at the same time you need to know the center of gravity of the car. And this is easy to calculate.

Most people know about buoyancy in water. But many do not know that it also applies to air
measurement of clamping force
มุมมอง 5305 ปีที่แล้ว
measurement of clamping force of several types of clamps
The reason I use steel bar instead of angle steel for short distances is that I have a powerful motorized press that presses flat angle steel when they get too short. For those of you who have a manual press, you only need angle steel fingers.
Are you using a pressure gauge?
Love that you do demonstrations 👍💯
Hi, thanks for your comment. Without demonstrations, the video is worthless
@@MyOyvind 💯👍
th-cam.com/video/zqeOh75IkzE/w-d-xo.html Please weigh the piece of wood for the first time vertically in a vacuum and then horizontally in a vacuum on an electronic scale
Bravo. You discovered that the air also works like buoyancy factor on the large (of course) wooden object and while inside the container it will work its minimal force making the piece of wood lighter (just like water only thousands of times smaller but the effect will still be there) You are finally up to the middle school physics books.
Thank you for finding my experiment interesting
Bravo! Bravo! Way to go! I am from Poland, thank you for this experience. It explains a lot in physics. Gravity is not what they teach us

Thank you for finding my experiment interesting
@@MyOyvind A very good experiment. Please check the weight of the wooden strip vertically and horizontally. See if there will be a difference in weight between vertical and horizontal?
@@MyOyvind I think the gravitational pressure is coming from above through the ether particles that tend to connect with the Earth's magnetic field. The larger the surface area, the greater the pressure of the particles from above.
There was a typing error during the calculation, but the answer is correct
This is very useful content. Thank you for making this video and being both succinct and informative!
what if you did it with the same test mass but with say led rather than wood ?
Hi, it is the volume that determines the buoyancy, not the density of the material.
@@yvindjohansen6595 yer I get that but when you remove the gas you remove the duoyancy so with the led you will not see so mutch of a change as it's can't degas
Hi the trunk in the tree consists of many pipes that have flaps that regulate the flow of water when it is alive. When the tree dies, these flaps close, so I do not think the air in the pipes is drawn out.
@@yvindjohansen6595 water can still move in and out that's why you can buy them wood stick air sent to make a room smell nice
Hi ok accept it, thanks for the interest in my video
Brilliant videos.. even though you have little views or subscribers.. keep it up because this is science.. and this is knowledge.. bravo. I always share your videos..
That's awesome experiment.. for sure it destroyed lotsa misconceptions
Very simply understood .. gravity doesn't exist.. it is the known science of atomic density.. Remove the medium and there are no atoms to be less dense than. Nothing floats an a vacuum.. everything weighs more.. as weight is simply the displacement of atoms.. take water and lift it up.. it returns to its balance level.. and there is no longer any weight or "gravity".. This experiment shows that.. Gravity was used as a theory word.. for many unknown sciences at the time.. now known.. ATOMIC DENSITY.. the reason why things fall and rise.. Atomic ionisation.. attraction and repelling.. E.m.w. diffraction.. what you think of as sunlight is a wave. And when it is blocked by an object it caused wave diffraction.. "gravity" bending light. And tides being diamagnetic.. from the sun and moon.. Gravity is a hoax. A misconception.. the higher you fly the more you weigh until a vacuum and no motion or flight can occur using air pressure.. ..
@@michaelveroni1380 nice
@@michaelveroni1380 Flat earth model is a hoax, young Earth creation is a hoax. Spherical Globe Earth is evidenced. The effect of gravity is evidenced. Items with varying density and mass want to meet at the center of Earth's mass at the same time when dropped from altitude. ....What is it with Relative Density flat earth model that keeps the varying dense and mass items from moving left, right, diagonal when dropped from a particular altitude? If I drop 10 different bowling balls with different densities and masses in our atmosphere or a vacuum chamber, they all contact the ground at the same time. Why aren't some of them veering left, right, diagonal? Or why aren't some of them contacting the ground before some of the others? Why is a more dense/more massive ball not contacting the ground before a less dense/less massive ball? Because there is an 'effect' or observable 'phenomenon' acting upon them. ....Now there are some Flat Earther cultists that claim their is Universal Acceleration instead of Relative Density that causes a gravitational 'effect.' But that has also been debunked, as measurements have been taken that shows Earth's gravity decreases with altitude and elevation. "...A misconception.. the higher you fly the more you weigh until a vacuum and no motion or flight can occur using air pressure.. .." Huh? What ?? A human weighs less at the peak of Mt. Everest than at Sea Level. This has been tested and measured. Flat earth cultists are trying hard to squeeze their model into reality, but it is being debunked and destroyed all the time. But keep up making videos that try proving a flat earther cultist model, because it is entertaining watching and learning how and why this model is debunked. And the spherical Globe Earth model is evidenced. Oh and here are a multitude of photos from before CGI or Photoshop that have the negatives that can be verified are real actual photographs of the moon missions. tothemoon.ser.asu.edu/
