No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

There's going to be a limit to how much pressure before stalling and/or damaging the engine, but it would inflate, and as the gases cooled, it would deflate somewhat.
Exhaust jacks are used in 4x4 recovery, so an engine can lift a car, but they seem pretty limited and dangerous and I've only seen one used once in my ~25yrs off road.
Okay hear me out, I know this is funking stupid but what if: We only use a portion of the exhaust and make some sort of system that can feed the gas to when wheels are spinning and monitor the pressure at the same time, then add a lining on the inside of the tires to protect the rubber.
These systems exist already, they just use a belt driven air compressor because it's ridiculously more practical/efficient.
I have an air compressor which is powered by the 12V DC outlet in a car. They are quite cost effective and easy to buy. I use it all the time to refill my tires. Much better than some odd exhaust pressure solution.
Rotating seals are always a pain in the ass.
Yeah, these guys suck.
Force = pressure x area
It's not that big of a feat. Using the very low estimate of 2.5psi from another comment about exhaust pressure, that means it can sustain 2.5 pounds(force) per square inch. To lift half a 5000lb suv the force needed would be 2500lbs. Rearrange the equation to [area = force/pressure] and it becomes [area = 2500lbs/2.5 lbs per square inch] so 1,000 square inches. Divide by 144square inches per square foot (12x12) and you get 6.94 square feet gives you 2500lbs of force from 2.5psi. Then to find that area from a circle, divide by pi and square root the result (rearranging area=pi*r^2 ) and you find that 2.5psi will lift the side of an SUV with a little less than a 3 foot diameter circle. That's about the size of the lift bags I've seen.
And all that while I'm thinking 2.5psi sounds low. Regardless, I doubt an exhaust system would handle anything close to tire pressure before popping off fittings. Plus mufflers have weep holes and fittings tend to leak anyway. They rely on the direction and speed of exhaust gas a fair amount.
