Engineering curves ellipse parabola hyperbola cycloid solved problems this ezed video explains engineering curves. The parabola is a conic section, the intersection of a right circular conical surface and a plane to a generating straight line of that surface. Conic sections an ellipse is obtained when a section plane aa, inclined to the axis cuts all the generators of the cone. To mark a tangent and normal to the ellipse at any point, say m on it, join the foci f 1 and f 2 with m and extend f 2 m to e and bisect the angle 0, the conic is a hyperbola. Although there are many equations that describe a conic section, the following table gives the standard form equations for nondegenerate conics sections.
