Udwadia–Kalaba Equation for Constrained Mechanical Systems: Formulation and Applications

Chinese Journal of Mechanical Engineering, 2018
There are many achievements in the field of analytical mechanics, such as Lagrange Equation, Hamilton’s Principle, Kane’s Equation. Compared to Newton–Euler mechanics, analytical mechanics have a wider range of applications and the formulation procedures

On the Origins of Hamilton’s Principle(s)

Encyclopedia
This entry first provides an overview of the historical, cultural and epistemological background that is key for Hamilton’s positions on mechanics. We consider the investigations on geometrical optics in the 17th and 18th centuries, Euler’s and Lagrange ...

Close Binary Stars Modeled by Two Prolate Ellipsoids in Synchronous Rotation

The Astronomical Journal, 2023
The presence of tidal deformations in close binary stars has already been confirmed by astronomical observations. The present paper aims to simply address an astronomy problem, studying the relative movement of close binaries disturbed by their mutual ...

A dinâmica de um elipsoide em rotação

Revista Brasileira de Ensino de Física
Um fenômeno físico interessante que contraria nosso senso comum concerne à dinâmica do movimento de um elipsoide em rotação numa superfície não lisa. Um elipsoide em rotação é, por exemplo, um ovo cozido, girando numa mesa de superfície áspera.

Novel Analytical and Numerical Approximations to the Forced Damped Parametric Driven Pendulum Oscillator: Chebyshev Collocation Method

Journal of Mathematics, 2022
In this work, some novel approximate analytical and numerical solutions to the forced damped driven nonlinear (FDDN) pendulum equation and some relation equations of motion on the pivot vertically for arbitrary angles are obtained.

Mechanical Foundations of the Generalized Second Law and the Irreversibility Principle

Foundations
We follow the Boltzmann-Clausius-Maxwell (BCM) proposal to establish the generalized second law (GSL) that is applicable to a system of any size, including a single particle system as our example establishes, and that supercedes the celebrated second law

Dirac Brackets and Time-Dependent Constraints

Universe
We provide a simultaneous derivation of the Dirac bracket and of the equations of motion for second-class constrained systems when the constraints are time-dependent.
