Introduction

Abstract

Mechanics is the oldest and the most highly developed branch of physics. As important foundation of engineering, its relevance continues to increase as its range of application grows.

The tasks of mechanics include the description and determination of the motion of bodies, as well as the investigation of the forces associated with the motion. Technical examples of such motions are the rolling wheel of a vehicle, the flow of a fluid in a duct, the flight of an airplane and the orbit of a satellite. “Motion” in a generalized sense includes the deflection of a bridge or the deformation of a structural element under the influence of a load. An important special case is the state of rest; a building, dam or television tower should be constructed in such a way that it does not move or collapse.
