"A Course in Mechanics" starts with the basic elements of mechanics: force, equilibrium of forces and motion followed by inter-relationships between them. From conditions of equilibrium of one force on one particle to those for system of forces in three dimensions along with the stability of equilibrium are thoroughly presented. Some special types of motion of an object based on Newton's law of motion in Cartesian, polar and intrinsic two dimensional frames comprise major portion of the book. Motion of an object as well as of rigid body in a rotating space like the Earth in addition to the rigid body motion based on D' Alembert's principle is also covered in the book.
