Learning Objectives

• STATICA
  

  The module of Statics aims at delivering studens the basic knowledge of the mechanics of structures, in view of the future courses of Mechanics of Structures and Design of Structures.

  In particular, as shown below in the contents of the course, after dealing with the basic topics regarding the equilibrium, the statics and kinematics of rigid bodies, several plane structural typologies subjected to forces were analyzed (beams, frames, articulated systems, arches).

  Such structures will be classified, characterized on the basis of a kinematic analysis, and the reactions and the force on the structure will be obtained.

  Finally, a part of the course will be devoted to topics which will be applied in future courses with reference to the stress and strain analyses. In particular, the geometric properties of plane figures will be inferred.

• FISICA
  

  Allow students to understand the scientific basis of modern technologies commonly used in professional practice and research.

• FISICA
  

  Physics will be presented to the students not as a collection of abstract formulas and ideas, as it is often perceived by students like those that are graduating in "Architecture", but as a tool for understanding the world around us and as a cultural basis for mastering and properly use modern advanced technologies now in daily use.

  Any book is accepted, provided is university level one. The concepts developped in this course are indeed indipendent from the Author views or research as we are dealing with well established classical physics subjects.

  Anyway, the course will more closely follow these textbooks:

  Fisica, Alonso-Finn, English and Spanish edition available at Addison-Wesley

  Physics2000, HR Huggins, Moose Mountain Digital Press, available at www.physics2000.com

  Fisica, P. Mazzoldi, M. Nigro, C. Voci, SES (italian)

  Problemi di Fisica Generale, Rosati- Casali, CEA (Italian)
