Lagrangian Mechanics Problems and Solutions
History of Classical Mechanics Classical Mechanics is one of the most important foundations of theoretical physics. The term "Classical Mechanics" refers to the system of mathematical physics that began in the 17th century by Isaac Newton based on the astronomical theories of Johannes Kepler and Tycho Brahe. This theory has been expanded and reformed by Lagrange and Hamilton. Lagrangian Mechanics is one of the two fundamental branches of Analytical Dynamics along with Hamiltonian Mechanics. It was formulated by the French mathematician Lagrange in the period 1783-88. In 1755 the Euler - Lagrange equation appears. At that time, both 19-year-old Lagrange and 48-year-old Euler are looking for a solution to the "equinox problem." Lagrange arrives at a solution in 1755 and sends it to Euler who processes it in order to arrive at a formula based on the Principle of Least Action, according to which the path of a particle is the one that yields a stationary value of the action. Quantum Mechanics can be established with aforementioned principle in conjunction with path integrals. The latter were introduced by Dirac and Feynman. The study of the problems of classical mechanics continued in the 20th century by great mathematicians such as Henri Poincare, reaching to date with the non-linear dynamics and the introduction of the concept of Chaos. Classical Mechanics is an inexhaustible source of new issues and concerns. This book aspires to be a small aid in the hands of the reader who wishes to begin his work with this great piece of physics, with a brief but comprehensive reference to theory and a satisfactory collection of solved exercises. Book presentation This book consists of 143 solved problems, accompanied by several images designed to enhance the understanding of the exercises. The fundamental theory is presented in a question-and-answer format, and each exercise is accompanied by a set of remarks and reminders. "Lagrangian Mechanics: Problems and Solutions" is tailored for undergraduate students of Science and Polytechnics. Key Features 1.

This approach can help readers see the relevance of the subject in various fields.
Essential Classical Mechanics: Problems And Solutions
'The authors of this book offer a very strong reason for the study of classical mechanics describing it 'as the base on which the whole pyramid of modern physics has been erected' … In order that students can gauge their understanding of the various topics, many exercises are introduced. Some of those should be straightforward whilst others are quite challenging … The authors are to be thanked for delivering a highly readable text which should assure a continued supply of practitioners of classical mechanics and its applications.'Contemporary PhysicsProblem solving in physics is not simply a test of understanding, but an integral part of learning. This book contains complete step-by-step solutions for all exercise problems in Essential Classical Mechanics, with succinct chapter-by-chapter summaries of key concepts and formulas. The degree of difficulty with problems varies from quite simple to very challenging; but none too easy, as all problems in physics demand some subtlety of intuition. The emphasis of the book is not so much in acquainting students with various problem-solving techniques as in suggesting ways of thinking. For undergraduate and graduate students, as well as those involved in teaching classical mechanics, this book can be used as a supplementary text or as an independent study aid.

The textbook Introduction to Classical Mechanics aims to provide a clear and concise set of lectures that take one from the introduction and application of Newton's laws up to Hamilton's principle of stationary action and the lagrangian mechanics of continuous systems. An extensive set of accessible problems enhances and extends the coverage.It serves as a prequel to the author's recently published book entitled Introduction to Electricity and Magnetism based on an introductory course taught some time ago at Stanford with over 400 students enrolled. Both lectures assume a good, concurrent course in calculus and familiarity with basic concepts in physics; the development is otherwise self-contained.As an aid for teaching and learning, and as was previously done with the publication of Introduction to Electricity and Magnetism: Solutions to Problems, this additional book provides the solutions to the problems in the text Introduction to Classical Mechanics.
