The modern software for Finite Element Method calculations is a powerful tool when making strength and stiffness calculations. However, this is only the case when FEM is applied correctly. This work contains all the information necessary for a thorough understanding of the FEM and its correct application:

- how are structures to be modelled into building blocks that can be used for calculations in an FEM program?

- how are FEM programs organised internally?

Hydraulic and lubrication systems have developed significantly in the past sixty years. The range of applications continue to expand. In modern systems, the application of proportional valves is a particularly important stimulus for the application of increasingly complicated and more accurate hydraulic drive systems.

With the availability of more accurate production techniques that enable the possibilities of minimal tolerances, the operating pressures have more than doubled in the last 25 y...
