## An Introduction to MechanicsThis text describes advanced studies in applied mathematics and applied physics. The text includes a discussion of vector analysis followed by its applications in particle mechanics and mechanics of rigid bodies. Each chapter contains solved problems and examples which help to illustrate the principles discussed in the chapter. The last two chapters deal with Lagrange's theorem and Hamilton's theorem and their applications in calculus of variations - a mathematical tool, needed in the study of applied mathematics and applied physics. |
