Found the uncensored version

Better quality uncensored version

I know this is obvious but it boggles my mind how each square inch of that tire has almost 100lbs of force pushing on it

Just realizing now why hydraulics are so strong, a 6 inch squared piston at 100 psi is 600 pounds of force

[–] [email protected] 1 points 5 minutes ago

If you consider that a car weighs hundreds of kilograms but its contact surface with ground is something like 100 squared centimetres, that pressure makes sense

[–] [email protected] 3 points 56 minutes ago

I work with industrial hydraulics, the forces involved in big gear are truly insane.

Working pressures is around 270bar....on ~1.4m^2 of cylinders. Millions of kg of force.

Why the fuck is the word shit "censored". What is the point of obfuscating a few pixels yet the word is still visible

[–] [email protected] 8 points 5 hours ago

people are so consistently mad about this in memes now I'm going to start including it in all the memes I make

[–] [email protected] 11 points 5 hours ago

Either OCR censoring or engagement bait for wherever it was originally

Its like you never heard of shπ.

Probably to dodge shitty social media OCR censoring

Bro I found it of reddit years ago and has been sitting in my meme folder bunkers since then. I don't know who did it

100psi is 6894 hPa for the freedom challenged among us.

[–] [email protected] 17 points 9 hours ago (1 children)

I find bar more intuitive even if it's just hPa/1000

Nearly 7 bar is impressive for any tyres

[–] [email protected] 8 points 6 hours ago* (last edited 6 hours ago)

Any car tire.

For road bicycles 7 bar is just "normal", 8 and above isn't unheard of.

A guy once asked if I was crazy when I was pressurizing my hybrid bike to 6 bar, and I just pointed to the sidewall where the rating said 4.5-6.5 bar. The range is wide because the pressure you should use varies depending on what you weigh, and how you want to balance rolling resistance vs comfort.

And even then the safety margin on bike tires is more than double the max rating, so it's perfectly safe to go a full bar over if you want.

How much banana per square dishwasher in is that?

[–] [email protected] 2 points 2 hours ago (1 children)

If we take the banana to be 180 grams and the square dishwasher to be 0.36 square meter, that would come to about 140,000 bananas per square dishwasher.

[–] [email protected] 2 points 1 hour ago

Nice math. Makes more sense then imperial, for sure. That's a lot of bananas, might as well go drive a banana car

I didn't know Torr was deprecated... For some reason that was always the number for STP I could remember in physics.

[–] [email protected] 15 points 10 hours ago

5171.49252 mmHg (millimeters of mercury)

why didn't you say that immediately??

[–] [email protected] 4 points 10 hours ago

Can you give me a reading in burgers needed to achieve that pressure in my heart?

[–] [email protected] 5 points 10 hours ago

How about 689.4kPa?

[–] EmoDuck 11 points 10 hours ago

Plot twist: That reading is in Bar

[–] [email protected] 93 points 15 hours ago (3 children)

I've stopped a half dozen people from doing something like this... Every single one of them was filling up to the maximum pressure listed on the sidewall.

The sidewall pressure is only the correct pressure at the maximum load on the tire. The maximum rated load on the tire is often nearly twice the vehicle's maximum weight rating, so the sidewall pressure is never the correct pressure for your vehicle.

The correct pressure for each tire on your vehicle is listed on a tag on the driver's door, or door frame.

Jup.

Cars actually come with manuals that explain this stuff.

Reading is a lost art.

[–] [email protected] 45 points 12 hours ago* (last edited 12 hours ago) (1 children)

I'm with you, I'm the one who read my wife's car manual.

One of life's pleasures, for me, is getting home with a shiny new thing and going over the manual and trying out the features, and of course it will work as described, and somehow that's very satisfying.

I might be on the spectrum though, my experience is that people find that weird and nobody bothers to read manuals.

[–] [email protected] 15 points 9 hours ago* (last edited 9 hours ago) (2 children)

One of life’s pleasures, for me, is getting…

Oh nice, me too!

I might be on the spectrum though

Ah, me too

[–] [email protected] 3 points 2 hours ago

Same, but in my line of work (programmer) it makes me look like a damn savant. "How did you know how to do X?" "Oh, I vaguely remembered something from reading the API docs 2 years ago so I just went and looked it up again"

[–] [email protected] 2 points 5 hours ago

Well fuck, am I on the spectrum?

Don’t forget also that tire pressure increases with temperature. You’re pressure will be higher if the weather is warmer, and will actually increase as you drive. A 30 mile drive could see a 4-5 psi increase.

Once my roommate punctured one of my tires and I went to a gas station and filled it up. Must have been one of my first times doing it ever. As I got back on the highway my car finally showed the pressure, it read 73….

[–] [email protected] 46 points 15 hours ago (2 children)

Don't feel bad ... I drove down the road once in my old truck and started feeling a terrible shaking ... I drove for a while hoping it would go away but it got worse. I finally pulled over and had a look at front passenger side tire .... a bulge was sticking out of it like a giant bruise and once the tire stopped moving, the bulge grew ten sizes and as soon as I realized what it was, I turned away and the thing exploded!

Always check your tires.
