Linear Friction Welding Friction welding is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called "upset" to plastically displace and fuse the materials. Friction welding allows dissimilar materials to be joined. This is particularly useful in #aerospace where it is used to join lightweight aluminum stock to high-strength steels. Other common uses for these sorts of bi-metal joins is in the nuclear industry, where copper-steel joints are common in the reactor cooling systems. ☄️ .

Floating Hourglass Puzzle: famous physics puzzle- why does the hourglass not start rising right away? The glass only ascends after about half of the sand has transferred to the lower bulb. The hourglass is a normal glass timer, it is submersed in plain water, and the main tube has an inner diameter which is at least 5mm larger than the diameter of the glass. A simple physics property of the hourglass changes and explains this behavior. I'll post the answer in a few days. Another puzzle made famous by Martin Gardner.⏳➡️ Answer: Thanks for all the creative and thoughtful answers! Here’s my best take- sand moves within any hourglass and the property of the hourglass that changes most significantly as the sand redistributes is its center of mass. When the assembly is initially flipped over the hourglass is very top heavy with all the sand in the top chamber so it tilts and presses against the wall of the tube with enough force that friction holds it in place. When enough sand moves to the bottom, the hourglass straightens up lessening the friction, and it then begins to rise. ➡️Follow the link in my profile for info on where to get many of the amazing items featured here on @physicsfun #physics #physicstoy #physicspuzzle #puzzle #buoyancy #hourglass #float #gravity #torque #force #friction #science #scienceisawesome #floatinghourglass

THIS WAS WHAT I MEANT BY PLAYTIME...the sun was out, spring was in the air, I’d just finished my back squats and conditioning like a good boy...so it was time to take my new ‘Push/Pull’ Sled reset drill for another run out...but this time on gritty concrete...and it’s a bit of a game changer. #FRICTION . . . You can see here how the rhythm sometimes breaks...but that’s part of the challenge - the ability to quickly reset in each new position for each new rep and still keep a strong body profile, a forceful centre of mass and decent overall power output! #SPORTS . . . Format: 30 secs on, 30 secs off. 10 rounds (in the sun catching some healthy VitD ideally ) . . . @andrefevo

Visualization of angular momentum. Angular Momentum itself doesn't cause the invert, the conservation of angular momentum does.  Think of the outer ring, or lighter mass as a 3d sphere that contains the heavier, smaller mass inside of it. If we input the same energy into both, but only apply a counter force to the smaller-mass "container", that friction force will "have more of a slowing effect" on the lighter container than the smaller heavier mass (this is called moment of inertia), and since momentum is conserved, it has to go somewhere, so instead of naturally sitting in the bottom of the container, it rises to the top. (Sort of like how a motorcycle is able to do a loop) then it gets unstable and wobbles down to it's natural position and this process repeats until the momentum is "used up" and the whole system stops. .

Just when I thought I was going to call this one finished, I decided it needed a good sanding. Something was bothering me about this painting from the get-go and I couldn’t figure it out until today. The textures on the face were distracting. Seriously, one of the most useful tools an artist has in their paint box is a sanding block. Even if it doesn’t fix the painting, at least it’s therapeutic. I’ll post the (hopefully improved) end result when I get it repainted. Share this video with your frustrated artist friends

For an #anklehang a flexed foot is preferable to a sickled foot for ankle....But WHY?!? . When you flex your foot you create a shelf at your ankle that your apparatus has to bend around. This sharp bend increases the friction and holds you up. . When you sickle your foot you wrap it around and conform more to the shape of the apparatus and give yourself less #grip. . So, it may feel like you are holding on, but with a flexed foot the apparatus holds onto you!!! . Want to know more about hanging from your hands? You can still join session 2 of my hanging boot camp!
