I have seen many answers to this question on the web and while all were correct in their intent, they were all technically wrong or ambiguous because they failed to use definitive language.
The minor and major axes lie perpendicular to each other in the plane of the cross-sectional area of the beam. The major axis bisects the area 'short-ways,' the minor, 'long-ways.'
Now if like me, you were confused in 1st-grade by the terms in quotes, the major axis is the one about which the greatest moment of inertia can be calculated. Or, if you think of the axes as wires laying in a puddle shaped like the cross-sectional area, the minor axis will have more of its length wet than the major axis.

The minor axis of a rectangular column or beam is the line that goes through the center. The minor axis will be shorter than the major axis.
The major axis is the axis that cuts, or goes between the two vertices of the hyperbola. The minor axis is perpendicular to the major axis and is an axis of symmetry. If the hyperbola is defined by: x^2/a^2 - y^2/b^2=1 where x^2 is x squared. Then the major axis is 2a units long, and the minor axis is 2b units long.
In a rectangle, the major axis is the longer of the two perpendicular lines that intersect at the center of the rectangle. It is also known as the length of the rectangle. The minor axis is the shorter of the two perpendicular lines, also intersecting at the center, and is referred to as the width of the rectangle. These axes are important in determining the dimensions and properties of a rectangle, such as its area and perimeter.
Minor axis = 20, major axis = 57 Perimeter of ellipse = 128 cms.
It is the conjugate axis or the minor axis.

The area of an ellipse with a major axis 20 m and a minor axis 10 m is: 157.1 m2
The major axis and the minor axis.
The depth of section is major axis of that section. Prependicular to that depth is minor axis of that section. I think it helps you to understand. Regards, Vinay
2, major & minor. (Yes, really!)
In a beam or length of material, we generally consider the longitudinal axis as the major axis for bending. But torsion will bend the material from the vertical, will twist it around that longitudinal axis. And lateral forces will bend the material across it axis of latitude.
An ellipse with centre (xo, yo) with major and minor axes a and b (the larger of a, b being the major axis) has an equation of the form: (x - xo)2 / a2 + (y - yo)2 / b2 = 1 The semi-major and semi-minor axes are half the major and minor axes. So re-arrange the equation into this form: 16x2 + y2 = 16 x2 + y2 / 16 = 1 (x - 0)2 / 12 + (y - 0)2 / 42 = 1 Giving: Centre = (0, 0) Major axis = 2 Semi-major axis = 2/2 = 1 Minor axis = 1 Semi-minor axis = 1/2

An oval,or more technically an ellipse, has a long ( major) axis and short (minor axis). If major axis length is a and minor length is b, then area, A is A = pi x a x b /4 where pi = 3.14 (approx)

The moment of inertia of an ellipse about its major axis (x-axis) is given by the equation I = πab^3/4, where a is the length of the semi-major axis and b is the length of the semi-minor axis of the ellipse.
