Curvature k and torsion of a helix C are in a constant ratio to the curvature k, of the plane curve C, obtained by projecting C on a plane perpendicular to the axis of helix i.e. they are connected by the relation t = k₁ sin a cos a k = k₁ sin² a where is the constant angle at which the helix cut the generators. and
