Technical Mechanics I (Statics)

The aim of the Technical Mechanics I lecture is to teach the concepts of force and moment acting on rigid bodies (i.e. not structures that we consider to be deformable). We are not only interested in individual forces, but also in spatially or surface-distributed force densities in order to be able to estimate the force flow in a component. We will initially restrict ourselves to static systems, i.e. systems that do not move. After an introduction to vector calculus, we therefore deal with force systems that are in so-called static equilibrium. Since loads distributed in volume and area are strongly connected in the calculation with a resulting force (moment), the determination of the center of gravity (and other terms such as center of line, center of area and center of volume, center of mass) is a topic to be dealt with. We then deal with simple structures made of pure bars and beams as well as the case of static friction.
