Effects of Seat Belts and Shock Absorbers on the Safety of Racing Car Drivers

Mathematics, 2022
This paper aimed to study the behavior of a body (dummy) that was in a race car in the event of a frontal collision with a wall in order to see what loads were acting on the dummy.

Exact and inexact differentials in the early development of mechanics and thermodynamics [PDF]

Revista Brasileira de Ensino de Física, 2019
We give an account and a critical analysis of the use of exact and inexact differentials in the early development of mechanics and thermodynamics, and the emergence of differential calculus and how it was applied to solve some mechanical problems, such ...

Numerical-analytical method in reinforced concrete mechanics

Structural Mechanics of Engineering Constructions and Buildings, 2022
A variant of the numerical-analytical method in the nonlinear mechanics of reinforced concrete is proposed. Calculation models make it possible to take into account a number of important factors, such as discrete cracks, the effect of concrete ...

Symmetries in central-force problems [PDF]

Serbian Astronomical Journal, 2003
The two-body problem in central fields (reducible to a central-force problem) models a lot of concrete astronomical situations. The corresponding vector fields (in Cartesian and polar coordinates, extended via collision-blow-up and infinity-blow-up ...

Hyperbolic normal forms and invariant manifolds: Astronomical applications [PDF]

Serbian Astronomical Journal, 2012
In recent years, the study of the dynamics induced by the invariant manifolds of unstable periodic orbits in nonlinear Hamiltonian dynamical systems has led to a number of applications in celestial mechanics and dynamical astronomy.
