Aims

Introductory course to magnetism and mechanics of rigid bodies.

At the end of the course, students are expected to be able:
1. to use the basic laws of electromagnetism in order to solve simple electromagnetical or electromechanical problems;
2. to express the movement equations of a rigid body supporting various forces in the vectorial form (Newton-Euler equations); to derive system motion equations in terms of generalized coordinates and their derivatives, for a system of interconnected rigid bodies;
3. to use a cutting method to compute a force (or torque) inside an internal link;

Main themes

The course is divided in two parts. The first one (2ECTS) continues the introduction of the fundamentals of electromagnetism; the second one (4ECTS) deals with the mechanics of rigid bodies. Both parts extend the skills acquired previously by the students during course FSAB1201 Physics 1.

The first part introduces basic laws of electromagnetism, and their applications in vacuum and matter as well (Biot-Savart & Ampere laws; magnetic induction, simple magnetic circuits). Induction phenomena due to variable magnetic fields (Lenz-Faraday laws, inductance) are then treated.

The second part starts with elements of 3D vector geometry needed to represent the instantaneous configurations of one or several interconnected rigid bodies. Next its derives the equations describing the dynamics of a single rigid body (Newton-Euler equations), and then it deals with the tools necessary to modelize rigid bodies dynamics (by means of generalized coordinates). Finally, it briefly presents some elements of rigid bodies static's (cutting method, iso- and hyper-static configurations,).

Content and teaching methods

Summary: content and methods

Part 1. Magnetostatics - induction - electromagnetic field
- Magnetostatics in vacuum

- Electromagnetic induction phenomena

Part 2. Mechanics of rigid bodies
- Vectorial geometry and kinematics in 3D
- Dynamic characterization of a rigid body (mass center, inertia, )
- Dynamics of a system of interconnected rigid bodies
- Static of a system of rigid bodies

Methods: Problem-based learning, exercises, lectures, practical classes

Other information (prerequisite, evaluation (assessment methods), course materials recommended readings, ...)

The evaluation has 2 components: an intermediary evaluation during the quadrimester and a final exam at the end of the quadrimester (written exam). The final mark is a combination of the scores in these two evaluations
