At the beginning the product design process as problem solving procedure for technical problems is explained with problem definition and customer demands
for the product. 

Following the basic loadings are discussed which machines and their parts under operating conditions are subdued. 

Further on the boundary forces of construction basic materials at static and dynamic forces are discussed.

The definition of the shape fatigue strength of real parts is given. 

Fits and tolerances are discussed as the last topic in the lecture.
