At 15 miles the drop is 141 feet. With an 8 inch mile curve you can start anywhere walk a mile in any direction and you will be 8 lower than from where you began.

How Much Does The Earth Curve Over A One Foot Distance Math Central

The Earth curves about 8 inches per mile.

. It does not account for the observers height and atmospheric refraction. To find the amount it curves in 1 foot you need to perform the the type. Rearranged h d²2r h.

The calculations go as follows. And therefore the rule is unsuitable to determine the amount of obstruction of a distant object due to Earths curvature. Answer 1 of 22.

The distance to the horizon in miles from height of an observer is approximately equal to 123 times the square root of the height in feet. Using the Pythagorean theorem that calculates to an average curvature of 798 inches per mile or approximately 8. I have tried keep the units simple in my example here.

The Earth has a radius of approximately 3965 miles. If an airliner is flying at approximately 500-600mph it seems to me that there would need to be a significant adjustment for altitude so as to not fly off into space. The eight inches per mile squared is a rule of thumb to determine the drop height due to the curvature of the Earth.

No matter how far you walk you will always be on the surface and therefore always the same height. As a result on a flat surface with your eyes 5 feet or so off the ground the farthest edge that you can see is about 3 miles away. Using the Pythagorean theorem that calculates to an average curvature of 798 inches per mile or approximately 8 inches per mile squared.

The Earth has a radius of approximately 3965 miles. The curve of the earth - or the drop - is not linear because the earth is a sphere- the cross section is a circle - and therefore the drop is not linear. Hence the earths surface curves at approximately 8 inches per mile.

For those in the know the most precise value of curvature is about 8 inches per mile. Convert miles to inches and h 8d². The Earth curves at about 8 inches for every mile squared but this distance is too minimal for a human being to discern the curvature.

How many miles can you see before the earth curves. Studies place the threshold altitude for seeing Earths curvature at about 35000 feet. If you want to bowl a strike - maybe you have to hit that first pin within a zone of 35 inches wide.

These are superior examples to any images. This means that for each mile of distance between you and another object the curvature obstructs approximately 8 inches of the objects height. Because h.

Earths curvature The Earth curves about 8 inches per mile. Because I use Mathcad units are handled automatically. Lake Pontchartrain Causeway is 39 miles long.

I say lower but in fact you will be exactly the same height or distance from the center of the earth. As a result on a flat surface with your eyes 5 feet or so off the ground the farthest edge that you can see is about 3 miles away23-May-2019. I should have said Hence the earths surface curves approximately 8 inches in one mile I will go back and change it.

R is the Earths radius h is the height of that object above the ground underneath. One thing you hear flat earthers say often is that the curvature of the earth is 8 inch per mile squared. What is the curvature of the Earth per meter.

At 5 miles the drop is 15 feet. 0000126 miles 1252800000126 798 inches. To show this let us return to the Pythagorean Theorem method used by Harley but using 6 feet for the curvature.

The Earth does have a curvature but almost nobody ever notices it because the value is very small. This is the globe earth math so let the globe earth insanity folks explain why Lake Pontchartrain Causeway or any other structure on flat earth has no curvature. I am not exactly sure what you are trying to compute but lets assume that you want to show that the Earth curves 8 inches over a mile of horizontal distance.

How many miles around is the earth. Curvature is said to be 8 inches X 39 miles squared 12168 inches 1014 feet. All of this reasoning is correct so far.

This is only a rough estimate for the first few mil. The Earth curves at approximately 8 inches per per mile squared. Eight Inches Per Mile Squared.

The surface of the earth is a curve and not flat so you cant use ratios. At 1 miles the drop is 6 foot. The width of the pin is about 45 inches 0114 m at the widest point.

Even while on top of Mount Everest it is impossible to see the curvature. How far can you see Earth curvature. Wikipedia says that theres an 8 inch drop for every mile because of the Earths curvature.

By saying 8 inches per mile it sounds like it will curve 16 inches in two miles and 4 inches in half a mile but this is not correct. For a six-foot-tall person the curvature is approximately 3 miles away. Thus your position is 3963000126 - 3963 0000126 miles above the surface of the earth.

However it turns out that while the earth does curve 8 inches in one mile it does not take 9 miles to curve 72 inches. At 10 miles the drop is 63 feet. Plug in the Earths average radius of 3960 miles for r and you get h d²7920.

This may be confusing for some.
