Teaching methods

The course is composed of two modules.

The first one (35 hours) provides main theoretical and practical knowledge and it mainly consists of lectures and exercises.

The second module (25 hours) provides the basics for the proper use of a CAD and it mainly consists of interactive lectures at the computer laboratories of the School of Engineering.

Assessment methods

EXAM

Oral and practical exam.

ORAL EXAM

It consists of two theoretical questions. The first one is the kinematic and kinetostatic analysis of a mechanism. The second one is on any other theoretical content of Module 1. The mark is the arithmetic mean of the two questions and must be no lower than 15/30.

PRACTICAL EXAM

The student will be asked to realize the drawing of a part by CAD or a mechanical simulation similar to those presented during the course (Module 2). The mark of the practical exam must be no lower than 15/30.

EXAM PROCEDURE

The oral and practical exams will be the same day. The final mark will be the arithmetic mean of the two marks of the oral and practical exam. The exam is positive if this mark is no lower than 18/30.

Teaching tools

During the course some presentations will be used to support theoretical topics. The material is made available on the "Insegnamenti online" website.
