Consider the special case in which the axis of rotation lies in the xy plane.

Such axes lie in a specific plane associated with this non-primary position.

Therefore the neutral axis lies on the centroid of the cross section.

The rotational axis of the Moon lies within Shackleton, only a few kilometers from its center.

The long axis lies along a line running northwest-southeast, with the wider girth located in the southeastern half.

If the axis of the rotation lies external of the body in question then the body is said to orbit.

The axis lies within the Greenwich observatory's meridian plane.

These threefold axes lie along the body diagonals of the cube.

The axes of the two curves must lie within the same plane.

Its shorter axis, about half that length, lies almost upon the equator.
