In high school we had an antique running track high above the gym. It was banked pretty much all the way around. Started out with a slight angle, and the further up you went the steeper it got. 30 degree will be fine. If I remember correctly it got way steeper than 30 degrees at the outside edge of the track.
Im often amazed at the amount of work you’ll put in on what I would consider silly projects, like an indoor running track. But then again I admire that you do put in the effort in what I would consider silly projects. It does look cool, I have to admit. Shown several people you building your house to show them what’s possible and how building codes and western house prices are ridiculous. You are one of my favorite channels, love the creativity and problem solving. Keep it going.👍👍👍
After having worked on several wooden boats, I've noticed that wood straps will hold that curved shape quite well after they've been in place for a period of time. Dan S. from Michigan and Texas
one nice thing about the tilt angled floor will be that it can 'self clear' of any buildup of stored or random items, as something like a wayward Lego would just slide off and then not be stepped on as you run the track .... I noticed this 'anti-clutter' effect on three surfaces I have(two drafting tables and a speakers podium) where the tops are slanted, you can only put so much on them(basically things you are actively using; like folding laundry, drawing papers, a laptop computer, book, or whatever that is pretty much flat and not a stack of that too high) until it all slides off onto the floor - always leaving a cleared surface ready for use
only 30% bank? I think you should floor the first 3 feet of the wall too in case you want to ride a bike, or an electric scooter! get a half "globe of death" going.
ha ha a nice tip sir. Once your done with cement and your hand are all raw and messed up you oil up all your wooden tools with a nice linseed oil. Yours hands will be smooth and moist again.
I’m pretty sure you can run on your track and the angle may even be quite good. Can’t make exact calculations, because I don’t know the exact size of your house, but assuming it has 10m diamater, ’optimum’ speed for 30 degree angle is 20km/h. That’s way more than jogging speed, but definitely what you can run. However, you’ll start to feel serious g-forces, so it’s not the same as in open track. Some may forget that mathematically optimal speed is not the same what you can run and steep is better than too flat. Mathematically optimal is pretty easy to calculate. It’s basically when the force is perpendicular to the platform angle. Gravity is always 1g down, and other component is centrifugal force. Relation of the two is tangent of the angle. With 30 degree tilt, it’s about 0.58, meaning centrifugal force should be 0.58g. It would increase your weight about 15%, so it’s like running with heavy backpack. You can count the required speed with formula v=sqrt(A*r), where v=m/s, A=centrifugal acceleration and r= radius in meters. Assuming 5m radius, v=sqrt(5*5.8m/s2)=5.38m/s=19.4km/h When word record runners run 500m, the average speed is around 27km/h. In 10km, it’s still 22.9km/h, although, they are not suffering 15% weight increase. I’m pretty sure you can run your track even 10km/h but be comfortable even if you take fast spurts.
Concrete water tank linings are impermeable and non-porous to water and most other liquid solutions1. These linings are used to create a waterproof coating on the surface of the tank to prevent leakages, contamination, and corrosion1. There are two common types of cementitious linings, which include epoxy and polymer modified cementitious linings2. These linings are ideal for waterproofing underwater retaining or collection structures2. Concrete is a highly porous material that absorbs water over time, and the lining acts as a barrier between the concrete and the water inside the tank, preventing the surface of the concrete tank from absorbing the water and sustaining damage3. Concrete poisoning can kill you if there’s no medical intervention. Poisoning occurs when calcium oxide present in cement reacts with water molecules to form calcium hydroxide. Unless it’s microscopically cleaned, the burn reaches internal organs, causing multiple organ failure and possible death.
Congratulations, you've used a planer to invent the world's worst jointer, with sides that are... kinda, not really at all square. But probably fine. Acceptable tolerances.
you don't have to "estimate" if 30 degrees is too much, you can literally do the high school physics calculations to find out at what speed your normal force becomes perpendicular to the bank. tell us the radius of the bank and I'll calculate it for you lol
He mentioned few times the size of the house. I forgot. I was something like 10 or 15 meters. But if you know the formulas, you can simply do the math for these two sizes and two more for us to get an idea. Anyway, even without owning the math too well, one can easily build an pendulum, rotate it, and see the angles on different speeds and get an idea. However, my thought is that they are able to run on it on 0 degrees. And maybe not full speed but still the body banks a little, and the ankles compensate. Then, when on the 30degrees, at full speed, if the body banks only 15 degrees, the ankles will compensate back. Sure, this will mean some discomfort.
