ABSTRACT
Annotation. Chapter 2 deals with natural oscillations in a simple mechanical sys-
tem with dry (Coulomb) friction. It includes a description of the simulated phys-
ical system and a summary of the relevant theoretical material for students as a
prerequisite for the virtual lab “Torsion Spring Oscillator with Dry Friction” from
the software package Physics of Oscillations (Part I, Simple Systems). Peculiari-
ties of damping of oscillations under dry friction are discussed in detail. Chapter
2 also includes a set of theoretical and experimental problems to be solved by
students, as well as various assignments that the instructor can offer students for
possible individual work on their own.
