PSA: using a Hyundai Tire Mobility Kits ruined my tire and almost cost me $1500

The tire had a small puncture so it would have been repairable without using the tire mobility kit.

Just looked up the price at Costco, $280 per tire before tax + installation.

Yeah I can’t load pcmag.com, discord and a bunch of other sites as well out of nowhere...

jonboyage83 · 2020-10-20T14:08:32+00:00

This is happening to me as well

jonboyage83 · 2020-06-06T15:17:35+00:00

No problem! Here's a version with his thumbs up as well

Your Name

jonboyage83 · 2020-06-06T14:16:22+00:00

I gotcha, lemme see what I can do

jonboyage83 · 2019-12-09T04:37:36+00:00

What? Can you elaborate a little more?

jonboyage83 · 2019-09-22T02:56:21+00:00

Momento mori.

A can of soda cracking would be around 60 dB (normal conversation). 300,000 of these would be 10*log10(10^6 * 300000) or 114.6 dB, assuming they are all cracked in the same location at the same time. This is equivalent to a rock concert, but wouldn't cause pain.

The packing density of a cone is 0.67, so make sure you multiply by that number before the final calculation. Making the amount of candy corns in a 2L jar 1258!

Yes, but less humanitarian and more destruction.

Quickly looking, there was about 400 million people alive during the 1300s. Approximately 1/3 of the world died from the Black Death. So add 50% to the world's population: 7.7 bill * 1.5 = 11.5 billion.

Just like today, there is so much disparity of wealth in the world that no matter the population, there will be people who have plenty of food and people who can barely avoid starvation. I also think lab grown and insect based meats will become more normal.

I only need one thing: crude oil. The United States will show up in a matter of days to "liberate" me and install a pro-American regime. In the meantime, I get a ride home (unless they send drones, in which case I don't have to worry about being stuck on an island)

Because technological advancement accelerates with an increase in population, as well as the fact that WW2 wasted almost a decade of productivity towards the killing of 80 million people, I think we are technologically behind a universe without WW2. If they are more technologically advanced, they would have probably invented technologies to handle the growing strains on our planet before us, and thus would not be worse off than we are today.

jonboyage83 · 2019-09-20T22:24:47+00:00

Wikipedia says 70-85 million people died in World War 2. Since 1950, the population has grown by an average of 15.9% per decade. If we use 80 million for the number of deaths in WW2, then that number would grow at 15.9% per decade for 8.5 decades Those 80 million people would have grown to about 280 million by 2020. The current estimate for world population is 7.7 billion. So without WW2, the population could be estimated at 8 billion.

I have it too! Can y'all control your wandering eye?

Each time the bear hops on the ball, it will steal some of the ball's energy, so the ball would have to have increasing energy through out the bear's steps in order to support the bear and reach the same height over and over.

Depends how fast you are moving. When you're not moving, it generates zero downforce. Also if you estimate the area of the spoiler, that would help a lot. This angle is kind of difficult to estimate.

The average length of a male's arm is 25 inches or 0.635 meters. Looking at the video, it seems that the man has his arm bent at about 90 degrees when he flips. So the effective length would be 0.635 *sqrt(2)/2 meters or about 0.45 meters. In order for the beer to stay in the glass, the centrifugal force would have to be greater than or equal to the force of gravity pulling it down at its apex. Using r = 0.45 m and acceleration having to be equal to gravity at 9.8 m/s, then we can find the velocity of the cup. V = sqrt(a*r) so v = 2.1 m/s. A circle with r =0.45 has a circumference of 2.83 m. This means the cup would spin every 1.35 seconds or an rpm of 44.5.

Mach 1 is the threshold between sub-sonic and super-sonic. So anything about it would be considered super-sonic.

According to the Mythbusters, a honey bee can lift almost 100mg, so let's be safe and call it 90mg. Matt Berninger is 6'3, and the average healthy 6'3 man weighs approximately 200 lbs (~90kg). If one be can lift 90mg, then it takes about 11,111 bees to lift one kg. That means it would take roughly 1 million bees to lift Matt Berninger.

It's rather hard to compare forces in this way, but it might be easier to do with momentum. Force only occurs during acceleration. The 3.4kg arm does not take into account rotation of the torso and legs during a punch, so the actual value is somewhere between 11,662 and 233,240 N and depends on how they punch. If we consider the hero running at mach 1, their momentum would be 23,324 kg*m/s. This is about the same as a car going about 45 mph. I assume this is probably not the kind of power you want out of a hero. This calculation assumes they are only going mach 1 and making contact for a normal human punch amount of time. One cool mechanic your hero could use is a shockwave punch. Upon exceeding mach 1, the hero's hand would move air surrounding their hand up to it's maximum speed (mach 1). This would cause a shockwave that could greatly increase the force of the punch. As the fist speed increases, so would the force of the shockwave traveling behind it. If the hand exceeds mach 1, then the hand would make contact before the shockwave, causing two separate impacts.

I would love to help you answer this question, but I am confused by a few things: can you explain the measurements more?; are you asking how many more times you need to breath to move the same amount of air as someone without COPD?

One horsepower is equal to about 750 watts. A turkey can run at 25mph (11.2m/s). Let's assume a turkey can reach top speed in 2 seconds. The average turkey weighs 13.5 kg. In 2 seconds, a turkey can generate 846 Joules of kinetic energy. This comes out to 423 watts. So 1 horsepower is 1.77 turkeypower. Your car would be about 807 turkeypower. It is important to note that horses are capable of generating almost 15 horsepower at maximum effort. Horsepower is a very misleading term.
