Solutions of Laplace's equation with simple boundary conditions, and their applications for capacitors with multiple symmetries
Mayckol Morales, Rodolfo A. Diaz, William J. Herrera
We find solutions of Laplace's equation with specific boundary conditions (in which such solutions take either the value zero or unity in each surface) using a generic curvilinear…
Study of the apsidal precession of the Physical Symmetrical Pendulum
Hector R. Maya, Rodolfo A. Diaz, William J. Herrera
We study the apsidal precession of a Physical Symmetrical Pendulum (Allais' precession) as a generalization of the precession corresponding to the Ideal Spherical Pendulum (Airy's…
Work and energy in rotating systems
Diego A. Manjarres, William J. Herrera, Rodolfo A. Diaz
Literature analyzes the way in which Newton's second law can be used when non-inertial rotating systems are used. However, the treatment of the work and energy theorem in rotating…
The role of the virtual work in Faraday's law
Rodolfo A. Diaz, William J. Herrera, Shirley Gomez
In the context of Faraday's induction law, we show that the concept of virtual work provides another point of view to clarify the nature of the induced electric field, as well as t…
The positivity and other properties of the matrix of capacitance: physical and mathematical implications
Rodolfo A. Diaz, William J. Herrera
We prove that the matrix of capacitance in electrostatics is a positive-singular matrix with a non-degenerate null eigenvalue. We explore the physical implications of this fact, an…
Work and energy in inertial and non inertial reference frames
Rodolfo A. Diaz, William J. Herrera, Diego A. Manjarres
It is usual in introductory courses of mechanics to develop the work and energy formalism from Newton's laws. On the other hand, literature analyzes the way in which forces transfo…
