ON THE DETERMINATION OF A DEVELOPABLE TIMELIKE RULED SURFACE

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: This paper gives a method for determining a developable timelike ruled surface by using dual vector calculus. A developable timelike ruled surface can be parameterized in the form m(t, u) =p(t) +u x(t) ( p(t) is called the base curve of m(t, u)).

On the curvatures of the ruled surfaces of b-lift curves

Cumhuriyet Science Journal, 2021
In this study, we defined a new curve which is called the B-Lift curve, also obtained the Frenet vectors of the B-Lift curve. The ruled surfaces have been produced by taking base curves B-Lift curves.

Lorentzian Beltrami-Euler formula and generalized Lorentzian Lamarle formila in R_1^n

Le Matematiche, 2009
In this paper, the sectional curvature of non-degenerate tangent sections of time-like ruled surface with the central ruled surface in n-dimensional Minkowski space, R_1^n  is studied. The relationship between normal sectional curvature and the principal

Involute Partner-Ruled Surfaces Formed by Involutes of Spacelike Curves in Minkowski Three-Space

Axioms
We introduced the concept of involute partner-ruled surfaces, which are formed by the involutes of spacelike curves and additional conditions ensuring the presence of definite surface normals in Minkowski three-space.

THE HYPERBOLOID OF REVOLUTION OF ONE NAPPE – A RULED SURFACE GENERATING CONICS

Journal of Industrial Design and Engineering Graphics, 2013
The paper intends to underline the property of the hyperboloid of revolution of one nappe to generate on its surface, when it is cut by a plane, the three known conics (ellipse, hyperbola and parabola).Cutting this surface by a plane, we find the ...

Geometric analysis of slant timelike-ruled surfaces and Bertrand offsets in Minkowski 3-space

AIP Advances
This study investigates the geometric properties of slant timelike-ruled surfaces and their Bertrand offsets in Minkowski space. By deriving their parametric equations, we examine the structural characteristics of these surfaces and classify their offset

Geometric Investigation of Three Thin Shells with Ruled Middle Surfaces with the Same Main Frame

Structural Mechanics of Engineering Constructions and Buildings
It is proved and illustrated that by taking the main frame of the surface, consisting of three plane curves placed in three coordinate planes, three different algebraic surfaces with the same rigid frame can be designed.
