Structure of the analytical physical theories

open access: yesRevista Brasileira de Ensino de Física, 2021
We present an analysis of the first analytical physical theories developed after the introduction of calculus. The underlying framework of these theories is the differential and integral calculus in the form developed by Leibniz.

Analytical mechanics allows novel vistas on mathematical epidemic dynamics modeling [PDF]

open access: yes, 2020
This contribution aims to shed light on mathematical epidemic dynamics modelling from the viewpoint of analytical mechanics. To set the stage, it recasts the basic SIR model of mathematical epidemic dynamics in an analytical mechanics setting.

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

open access: yesMathematics, 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.

The Foundation of Classical Mechanics

open access: yesEncyclopedia, 2021
Mechanics is the science of the equilibrium and motion of bodies subject to forces. The adjective classical, hence Classical Mechanics, was added in the 20th century to distinguish it from relativistic mechanics which studies motion with speed close to ...

Application of Genetic Algorithm Elements to Modelling of Rotation Processes in Motion Transmission Including a Long Shaft

open access: yesEnergies, 2020
Genetic algorithms are used to parameter identification of the model of oscillatory processes in complicated motion transmission of electric drives containing long elastic shafts as systems of distributed mechanical parameters.
