The propagation of a pulse in the real string and rods

TL;DR

This paper investigates how a pulse propagates through a large elastic string connected to small masses at both ends, with implications for quark-string models of mesons, providing insights into wave dynamics in such systems.

Contribution

It introduces a model analyzing pulse propagation in a string with fixed and attached masses, relevant to quark-string meson models, and derives the system's wave behavior.

Findings

Pulse propagates with specific characteristics in the system

The model relates to quark-string meson dynamics

Wave behavior depends on mass and boundary conditions

Abstract

The elastic string (rod) of a large mass M is considered, the left end of which is fixed to a body of a small mass m. The second body of mass m is fixed to the right end of the string. The force of the delta-function form is applied to the left side of the string. We find the propagation of a pulse in the system. The problem is related to the quark-string model of mesons.
