(3956.5467 miles) you get: 8.006982…For measurements along Earth's Polar radius (3949.9028 miles) you get: 8.020451…You can just see someone thinking.. "meh, 8 inches is in there somewhere". Why 8" per mile squared is wrongNow we can compare our better formula with this [8"×d²] estimation formula, I'll compare for Earth radius of 3959 miles: Earth Radius 3959 Distance (miles) Actual Drop (miles) Estimated Drop (miles) ERROR (miles) 1 0.000126 0.000126 0.000000 10 0.012629 0.012626 0.000003 100 1.262744 1.262626 0.000118 1000 124.341891 126.262626 -1.920735 2000 476.502339 505.050505 -28.548166 3000 1008.260915 1136.363636 -128.102721 3959 1639.871493 1979.000126 -339.128633 4000 1668.937544 2020.202020 -351.264476 From this is it easy to see that [8"×d²] is somewhat accurate for distances up to about 100 miles and then it is absolutely terrible after that. And now we know why - they threw out all the little corrections in the Taylor series that keep it accurate in order to make a simple "rule" that was "good enough" for what they needed at the time.So my advice is to gently inform those using it that it's only fairly accurate to about 100 miles but don't fret a few inches here and there when discussing the 'curvature' of the Earth.The more important issue to address is... Why It's Even More Wrong Than ThatBut more importantly, this [8"×d²] formula only gives you this somewhat wrong value for Drop Height, when what we actually care about, almost universally, is the height of a distant object that would be obscured for an observer at some elevation (h₀). I derive the correct formula to use for (h₁) height hidden by curvature at some distance in my other blog post but here is the short version:Additional NotesThere are TWO other ways to potentially measure Drop Height.The first one (which is the most common mistake) would be to

29 Mar 2024 Tags: Mechanical Engineering Engineering Mathematics Curvature and Radius Degree of curvature to radius calculator Popularity: ⭐⭐⭐Degree of Curvature CalculatorThis calculator provides the calculation of degree of curvature from radius.ExplanationCalculation Example: The degree of curvature (DOC) is a measure of how curved a circle is. It is defined as the angle subtended by an arc of the circle that has a length equal to the diameter of the circle. The DOC is typically measured in degrees.Q: What is the relationship between the radius of curvature and the degree of curvature?A: The degree of curvature is inversely proportional to the radius of curvature. This means that as the radius of curvature increases, the degree of curvature decreases.Q: How is the degree of curvature used in practice?A: The degree of curvature is used in a variety of applications, including the design of roads, bridges, and other structures. It is also used in the manufacture of lenses and other optical components.Variables| —— | —- | —- |Calculation ExpressionDOC Function: The degree of curvature is given by DOC = (D / 2) * (180 / ?)Calculated valuesConsidering these as variable values: R=100.0, D=200.0, the calculated value(s) are given in table below| —— | —- |Similar Calculators calculation for radius of curvature of a spline curve radius formula calculation chord radius calculator calculation for Calculations radius of gyration calculator calculation for Calculations spline curvature calculation radius of gyration calculator calculation chord length to radius calculator calculation for Calculations wheel radius calculation calculation for Calculations geometry calculator circle calculation for Calculations calculator geometry calculation for Calculations Explore Geometry Circles Curvature Calculator Apps Gear Design in 3D & Learning Matching 3D parts for degree of curvature to radius calculator calculation Angle Tee, Male, Equal (IS 1239) Spherical Gear (Z-axis) Elbows (Equal, 135_, IS 1239) Union Bends with Hexagon Nut (IS 1239) Cross (Reducing, IS 1239) App in actionThe video below shows the app in action.. What is the Curvature of the Earth Per Mile? Understanding Earth’s Shape. Defining Curvature; The Impact of Earth’s Radius; Calculating Curvature. Using the Pythagorean If the Earth were flat, we would expect a curvature rate of zero inches per mile. As it is, the Earth is not flat, and it's curvature rate is 8 inches per mile. 63,360 inches are in a mile, and

The curvature of railroad tracks must be carefully engineered to allow the trains to transit as a safe speed whilst maintaining stability. This simple Railroad Curve Calculator allows you to calculate the degree of curve by entering the radius of the curve. Railroad Degree of Curve Calculator Enter Radius Railroad Curve Calculator Results Degree of Curve = This tutorial provides an introduction to the concept of the Railroad Curve Calculator, a tool used in engineering disciplines to calculate various parameters related to railroad curves. The article covers interesting facts about railroad curves, explains the formula used in the calculator, provides real-life examples of its applications, and includes detailed instructions for its usage. Interesting Facts about Railroad Curves Railroad curves play a crucial role in the design and construction of railways. Here are some interesting facts about railroad curves: The curvature of a railroad curve is measured in degrees per unit length, typically expressed as degrees per 100 feet or degrees per 100 meters. The sharper the curve, the higher the degree of curvature. Curvature is denoted by the symbol "C." Curvature affects the speed at which trains can safely travel around a curve. Higher curvature requires reduced speeds to prevent derailments. Railroad curves are often banked or superelevated to counteract the centrifugal force acting on trains as they navigate the curve. This helps to maintain stability and passenger comfort. Formula for Railroad Curve Calculator The Railroad Curve Calculator employs a formula based on the degree of curvature (C), the length of curve (L), and the radius of the curve (R). The formula is as follows: R = 5729.57795 / C L = R × 2 × π × (C / 360) Where: R is the radius of the curve. C is the degree of curvature. L is the length of
