Geometry of the areas: area, center of gravity, static and inertia moments, main moments of inertia, notable cases. 6. Elastic instability. Access to the course's Google Classroom site will be made available two weeks before the start of the lessons. This site will not only provide all the information related to the course but will also be used to share study materials and communicate with the students.

Knowledge of the topics covered in the course of Institutions of Mathematics I in the first year. In particular, consolidated knowledge of matrices and vectors, operations between matrices and vectors, elements of linear algebra and systems of linear equations are required. At the beginning of the course will be made references to the main mathematical tools necessary for the treatment of the topics in such a way that attending students can fill specific or general gaps.

The teacher at the end of each lesson will provide some notes on the illustrated topics. For an in-depth study of the topics covered, below are some possible books. D. Capecchi, M. De Angelis, V. Sepe, Cinematica Piana dei Corpi Rigidi, CISU, Roma, 2005. D. Capecchi, M. De Angelis, L. Sorrentino, Statica Piana dei Corpi Rigidi, CISU, Roma, 2008. D. Capecchi, Teoria Tecnica della Trave Deformabile, CISU, Roma, 2007. Alternatively to the three books above: Scienza Delle Costruzioni, Paolo Casini and Marcello Vasta, CittàStudi, 2008.

In presence and by remote.

Attendance to the course is not mandatory. However, the greatest possible attendance is required.

The exam consists of a practical part to be performed in written form and a theoretical part to be performed in part in written form and in part in oral form, or entirely in oral form. Around the end of october or the first week of November, students can take a first partial test (exemption) on topics 1 and 2 listed in the tab "Program". The test consists of a practical test and a theretical test both to be executed in written form. Who achieves a grade of at least 18/30 in the practical test and the theoretical test, respectively, will be exempted from topics 1 and 2 in subsequent tests. On the last day of class it is possible to take the second partial test (only those who have successfully taken the first partial test on the practical part) on the remaining topics (practical part in written form) or repeat/perform the first partial test. Those who successfully take both partial tests will have to take only one oral test on the remaining topics. Those who successfully take only the first partial test must take a written practical test and an oral theoretical test on the official exam dates. Finally, for those who do not pass or do not perform the exemptions it is possible to take the entire exam on official dates by taking a written practical test and an oral theoretical test. After completing all the assessments, a grade will be assigned for the practical part and another for the theoretical part. Both scores, out of thirty, will be calculated as a weighted average of the grades obtained in the first part (weight 0.4) and the second part (weight 0.6) of the program. The final grade will be the arithmetic average of the total scores obtained in the practical and theoretical parts. Candidates who achieve a final grade of 30/30 will have the discretionary opportunity to earn honors through additional questions and/or exercises. The assessment methods for non-attending students do not differ from those for attending students. The contents of the practical tests consist in exercises that will be widely treated in class and of which many examples will be provided on the Classroom website. The theoretical tests consist of questions and demonstrations related to the topics that will be treated in the lessons. The methods of evaluation described above may be subject to changes that will be discussed and agreed in the classroom.

Teaching will take place exclusively in person, except in cases where classrooms are unavailable due to graduation sessions or other institutional events. Google Meet and Zoom platforms may be used for consultations. Lectures will primarily involve the instructor using the chalkboard to explain topics. The theoretical discussion will be followed by a practical part where exercises are performed. Both the theoretical explanations and especially the exercise sessions will be characterized by strong collective interaction. Students will also be asked to voluntarily complete exercises prepared at home.
