Abstract The Euler-Savary formula is a well-established relation with multiple interpretations.
This formula is revisited and cast as a geared three-link spatial mechanism with uniform …

Symmetry is a frequently recurring theme in mathematics, nature, science, etc. In
mathematics, its most familiar manifestation appears in geometry, most notably line …

In this study, the timelike-ruled and developable surfaces are constructed in Minkowski 3-
space E 1 3. Using the E. Study map, we demonstrate that dual forms of timelike-ruled and …

In this paper, based on the E. Study map, clear terms are offered for the differential
equations of one-parameter Lorentzian spatial kinematics that are coordinate system …

In this work, we introduce a time‐like ruled surface in one‐parameter hyperbolic dual
spherical motions. This provides the ability to derive some formulae of surface theory into …

In this paper, we analyze a certain class of timelike ruled surface in one-parameter
hyperbolic dual spherical motions by means of the E. Study map. Then, some new formulae …
