That was a mouthful. To be more precise, this question spawned out of my curiosity on how to explain to someone which side of a driveway I parked on if I parked on the street without knowing the direction or any external information except the fact that I am on a specific side of the driveway. Is there a word for the 2 respective locations I could be on each side of the driveway with only the end of the driveway and the street for reference?
North, South, East, West, left, and right are all not words I'm looking for.
Sorry if this is obnoxiously specific lol
EDIT: Now that I think about it, it would make more sense to include the direction of the car and the direction that I came from into the equation. So for more clarity and options, is there a word for being on one side of the driveway relating to the direction I came from? For example: I'm on the x side of the driveway, or the side that was closest to park on, or I'm on the y side of the driveway, or the side that I had to drive farther to pass the driveway and park on the curb.
Is it possible for there to be a planet whose magnetic axis is perpendicular to or greatly tilted from its rotational axis?
If so, what could cause such planet to have a magnetic field perpendicular to its rotational axis and what would its effects be on the planet itself?
the title basically. i understand how c=ea and how, for a horizontal ellipse x=(+/-)(a/e), but all of that given the directrices are parallel to the normal axis (minor axis/segment).
I tried deriving a general equation of an ellipse from the locus fact that the ratio of the distances from: a point on it to a focus, to a point on it and a line, is constant (e); all this with an arbitrary line L: px+qy+r=0, but ended up with a hot mess.
i was used to the eq of an ellipse being defined with the locus of constant foci distance equation and now this alternative definition comes up and I got confused.
also, is there a way to show they're equivalent? [constant sum(point, point)] <=> [constant ratio(point, line)]
Also known as the tennis racket theorem. Where when you flip an object around the intermediate axis it will flip back and forth? Veritasium did a video on it, and I tried to recreate it in space engineers with no luck so far. Thrusters don't apply any rotation, so that didn't really work. I tried rotors, but the object simply rotated in place, I believe that it is because it was too close to a "perfect" rotation. After detaching it, nothing had imposed any offset, and so it could not get enough force to swap side. If you guys have any ides, let me know! I would love to get this working.
Further, if it does not prove so in and of itself what other theorems/ proofs are needed?
Just like the title is asking, is it possible for a planet or celestial body to have rings orbiting perpendicularly to its "host". Additionally is it possible for a body to have rings rotating in the opposite direction of the "host's" rotation.
Let's say you have a stationary circular saw blade that is rotating with 5000-6000 1/min.
The blade is 250mm in diameter and has a weight of 300g.
What would happen if you suddenly start to move it perpendicular to its rotational axis with 16m/s and then stop the movement?
Or to simplify the question: There is that thing called sawstop for circular saws where it detects when flesh-like material is touching the blade and then it retracts the blade and brings it to an abrupt stop by having a soft metal crash into the blade.
Why do they stop the blade that way? If you move the blade away fast enough so that your fingers can't reach it anymore, wouldn't it be sufficient to simply cut the power and let the blade run out?
