sorry 100 miles
i need something that works with a whole sphere
or 24,000 miles
we arent on a 100 mile big sphere
Well, let's see.
8 inches*100^2= 80,000
7.98 inches*100^2= 79,800
200 inch difference after 100 miles. Because rounding
It is calculated from an approximately 25,000 mile circumference sphere
so 7.98 inches per mile squared wotks for a full sphere?
works
A sphere with a radius of 3,963 miles
im gonna have to research this
It assumes earth is a perfect sphere, but for general purposes, that assumption works even considering the model states it as slightly oblate
because did u see the thing i said earlier about man a man b and man c all in a straight line 1 mile apart?
man a to man b 8 inches of drop then from man b to man c 8 inches of drop but from a to c is 32 inches of drop that doesnt seem possible where did the extra amount of earth come from to drop
sorry im not great with math but reality i can handle fairly well
From the curvature.
If it was 16 inches from a to c instead of 32, it wouldn't be curve. Instead, it would be like you are on a cone, a straight line slope.
i understand why the math needs to work but in reality where did the extra earth come from somehow
from a to b its 8 inches right
and b to c is 8 inches
ur telling me that would never make a circle ?
Yes, 8 inches of drop over one mile, but a curve would have it drop away exponentially or else it would be a straight line. So, a to b, 8 inches of drop, b to c, 8 inches, a to c, 32 inches. You are thinking about this in terms of slopes on a coordinate plane, that doesn't apply here. This is a curved surface we are talking about
idk like i said im gonna have to look into this more
It might be easier to see this in a picture rather than in words
well first im gonna see if i can graph out both formulas to be a straight line
Try it
idk how to do th at
is their a website i could graph it on
Try this:
https://www.desmos.com/calculator
how do u make lines in that
thats some sweet graph paper better than the one i found lol
i wouldnt even know how to start graphing it even if i could make lines
Right, this might not be very good for this purpose.
You put in equations. Like, something simple, x=8, or y=4
For a circle, that is
(x-h)^2 + (y-k)^2 = r^2
hang on im watching some youtube vids on this subject
(x-h)^2 + (y-k)^2 = 3,953^2
And you get the cross section of the spherical earth since r for radius is about 3,953 miles
Idk how to do best represent the 7.98 inches per mile squared with this, probably better to just look for pictures
i just watched one and 8 inches per mile squared didnt work for a quarter of the globe it was way off
can u link youtube videos in here?
I think you can
he makes it look pretty clear the 8 inches per mile squared doesnt work
is that guys math wrong ? is the formula for the curvature of a sphere under debate ?
