The Major Axis of Elliptical Segment is the chord passing through both the foci of the Ellipse from which the Elliptical Segment is cut. It represents the longest diameter of the elliptical segment.
The calculator uses the formula:
Where:
Explanation: This formula simply doubles the semi-major axis to obtain the full major axis length of the elliptical segment.
Details: Calculating the major axis is essential in geometry and engineering applications involving elliptical shapes, particularly when determining the overall dimensions and proportions of elliptical segments in various designs and constructions.
Tips: Enter the semi-major axis value in meters. The value must be positive and greater than zero. The calculator will automatically compute and display the major axis length.
Q1: What is the difference between major axis and semi-major axis?
A: The major axis is the full length of the longest diameter of the ellipse, while the semi-major axis is exactly half of this length.
Q2: Can this calculator be used for complete ellipses?
A: Yes, the same formula applies for both elliptical segments and complete ellipses when calculating the major axis from the semi-major axis.
Q3: What units should I use for input?
A: The calculator accepts meters as input, but you can use any consistent unit of length as long as you maintain the same unit throughout your calculations.
Q4: Is the major axis always the longest dimension?
A: Yes, in an ellipse or elliptical segment, the major axis is always the longest diameter that passes through both foci of the ellipse.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact, provided the input value is accurate. The result's precision depends on the precision of your input measurement.
