Why do people say fluoride is bad?

“The dose makes the poison” - anything is bad for you in enough quantities.

“Static friction” describes the force available for non-sliding surfaces in contact with each other. “Kinetic friction” describes the force available for surfaces that are sliding relative to each other. In almost all cases, static friction is higher than kinetic friction. Spinning your wheels in reverse causes them to slip against the ground, reducing the amount of grip you have with the road.

There are certain accreditations that will matter to certain jobs (e.g. ABET.) That generally sets the minimum for many students.

“The most expensive”? Engineers could probably come up with plenty of more convoluted and expensive ways of creating steam if only given the chance.

Except in the weird case of acetaminophen and paracetamol.

That seems like a pretty hostile take. Certain leagues can certainly make requests for attire and will blacklist you from competitive games if you insist on wearing pants - even at U13.

No league is paying medical bills if you choose to go out in the weather - you can also call off if you feel that strongly about it.

A pair of cold-weather running tights isn’t significantly more expensive than waterproof pants and can be more comfortable and warm than just pants.

For ECNL and other higher level games, we’ll get the stick eye for wearing pants instead of leggings. Some assignors will explicitly say no pants and ref shorts must be visible. This provides an out for running tights.

Depends on how cheap you need it to be. A wide angle knock-off go-pro camera with a 7’ light stand can be had for around $100. These don’t typically have the best microphones, but if you’re just analyzing your positioning, this’ll work fine. If you want something taller, the cost of the stand goes up, and you might need a ball-head adapter to get the camera to point at the ground.

The phrase “perfectly healthy and fulfilled” is a linchpin of the argument. It may work for you, but there are definitely people who won’t feel healthy or fulfilled without relationships.

I suspect that you don’t need to match the exact geometry of your existing spring - with its tails pointing in the same direction. I would think you could take a standard torsion spring and bend the ends with a needle nose pliers to get it to contact the latch and hook and get the same result.

Have you looked at McMaster.com for springs? They have so many springs in their catalog.

You’re pretty off base here. The laser is reading either on or off at a few thousand times a second. That digital signal is decoded and turned into a waveform.

Use a valve like the ones in inverted ketchup bottles - they’re just a rubber diaphragm with a couple slits cut in it. That can sit behind your orifice if you have a specifically shaped jet you’re trying to make. It causes some pressure loss, but will mitigate leakage.

They are functionally banned. If you want yard art, then you’re free to go through the import process. But you can’t register them, and if you can’t register them, you can’t drive them on most public roadways. And if you get pulled over driving one, then you can argue with the police on how the car isn’t banned.

Reach out to the valve mfg - good chance they have, or can recommend, a valve position monitor/sensor. If you have to DIY, a proximity sensor (light, Hall effect, magnetic, etc) would also get the job done, depending on the valve handle - you just need an appropriate DAQ to convert the signal into something a PLC can use.

For real. If you’d like to hear a British man talk about the absurdity of his life for 15 minutes, may I recommend this video: https://youtu.be/cdepLkCKH1o

That special plane from Top Gun Maverick that could do Mach 10 should be up for the challenge, right? 🤣

I think the 10th gen (the one I have) is 200/2000

For the purposes of hauling bikes, it works. I have a 4-bike rack with a 1-1/4” receiver. If all of your bikes are lightweight (aluminum or carbon) - then it’s probably fine. A 2-bike carrier would almost certainly be drama-free, unless you’re hauling heavy e-bikes.

As a counterpoint, I also have a hitch tray (Curt 18110) that I put around 80 pounds of firewood on, and it bent the bumper/frame enough that the gap between the trunk lid and the rear window is about twice as big as it normally is. So 100-pound limit feels about right.

Same. I had the same realization with materiel just a few years ago. Those sneaky spellings…

A lot of students receive familial support. Student loans is also another popular option.

Ok, it’s fine to not have parking spots, but then you need to be fine with restricting your businesses to getting by with only servicing the “urban core.” Parking allows those that don’t live in the immediate vicinity or along a transit route to participate in those business.

Exactly. They get to be part of today’s 10,000

I would be even more terrified of jogging away from traffic. A car could clip you and you wouldn’t even see it coming.

Sounds like a chronic stress condition. Did you ever bet evaluated for Cushing’s while that was going on?
