Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

  • Reminders of mechanics of particle
  • Forces and moments of force
  • Force systems
  • Static equilibrium of a rigid body (in translation and rotation, in 2D and 3D)
  • Equilibrium with distributed forces (mass centre, hydrostatic pressure, friction)
  • Kinematics of a rigid body (translation and rotation in 2D)
  • Dynamics of a rigid body (translation and rotation in 2D, moment of inertia)

Learning outcomes of the learning unit

After completing the course, the students will have reached a novice skill level in the different development stages :

  • Design and size infrastructures and rural engineering structures such as dams, hydraulic structures, structures in steel, concrete and wood
  • Design and size equipments pf monitoring and production in an agroenvironmental context
  • Choose and size systems of purification, sanitation or renewable energy production
Particularly, after completing the course, the students will be expected to
  • Represent a body or system by a mechanical model, i.e. construct a free-body diagram
  • Establish and solve the equilibrium equations (with concentred and distributed charges) to find reactions
  • Compute mass centres and moments of inertia
  • Describe the movement trajectory of a rigid body
  • Establish and solve the movement equations of a rigid body

Prerequisite knowledge and skills

Mechanics of particules (theoretical concepts et resolution of exercises)

Planned learning activities and teaching methods

Theoretical course (12h) and practical work (12h)

Mode of delivery (face-to-face ; distance-learning)

Theoric lectures in face-to-face with demos to understand the basic concepts
Video sequences to help for the resolution of basic exercices.
Practical sessions in classroom to apply the theoretical notions.

Assessment methods and criteria

For the 1st and 2nd sessions, a written examination without note is organised on (i) fundamental theoretical concepts and (ii) resolutions of mechanical problems. For the case of success for the theoretical part, this will be moderately weighted with respect to the exercices. In contrast, if the theoretical part does not satisfy, this part will be restrictive for the final score, according to the following relation:
Total = min ( theory + 2 ; weighted average )  [if theory not succeeded]

Assessment subjects

The assessment subjects are the same as in first session.

Assessment methods

A written exam will be held remotely on the eCampus platform.
The examination will consist of (i) close theoretical questions assessing the understanding of the fundamental concepts of the course and (ii) open exercise questions integrating several parts of the course.
The examination will be limited in time. Alternatives will be provided depending on the technical and/or computer problems encountered during the examination.
Practical details are communicated to students on the eCampus page of the course.

Contacts

A forum is available to students on the eCampus page of the course. In case of problems, please contact Prof. B. Mercatoris via benoit.mercatoris@uliege.be
