This book examines the study of mechanical systems as well as its links to other sciences of nature. It presents the fundamentals behind how mechanical theories are constructed and details the solving methodology and mathematical tools used: vectors, tensors and notions of field theory. It also offers continuous and discontinuous phenomena as well as various mechanical magnitudes in a unitary form by means of the theory of distributions.
Mechanics has been at the heart of theoretical physics, ever since Ernst Mach's seminal work on the subject
Presents a thoroughly up-to-date treatment of the fundamentals behind how mechanical theories are constructed
The author has spent a lifetime studying this subject and brings together all of his experience and thought on the mechanics of particles into this volume
Comprehensive with references to over 600 books
