Aims of the course

-review some of the most important topics of kinematics and statics -acquire general overview about problems of architectural and structural design and construction through site visits at: an existing building,

a material testing laboratory, a construction site, and discussing the experiences gained at the above visits -making preparatory steps in numerical problem solution in the field of kinematics and statics: resultant and equilibration of coplanar forces -help to decide definitively to continue studies in architectural (or civil) engineering
