# Eccentricity e of a cylindric section

## Description

Eccentricity e of the cylindric section and semi-major axis of the cylindric section depend on the radius of the cylinder and the angle between the secant plane and cylinder semi-major axis .

Cylindric sections are the intersections of cylinders with planes

## Variables

e | Eccentricity e of the cylindric section (m) |

r | Radius of the base of the cylinder (m) |

a | Angle between the secant plane and cylinder semi-major axis . (degrees) |
