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, hybrid learning)

Face-to-face and/or remote theoric lectures with demos to understand the basic concepts
Video sequences to help for the resolution of basic exercices.
Practical sessions in inverted class with face-to-face and/or remote Q/A sessions.
 

Organisational adjustments related to the current health context

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

written exam ( multiple-choice questionnaire, open-ended questions )

- Remote

written exam ( multiple-choice questionnaire, open-ended questions )

- If evaluation in "hybrid"

preferred in-person


Additional information:

In 1st and 2nd sessions, a written examination without note is organised on (i) the fundamental theoretical concepts and (ii) the resolution of mechanical problems. The theoretical part is weighted at 1/6 and the practical part counts for 5/6.
