Number of credits

 Bachelor in bioengineering2 crédits 

Lecturer

Benoît Mercatoris

Language(s) of instruction

French language

Organisation and examination

Teaching in the first semester, review in January

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 course


Additional information:

Face-to-face and/or remote theoric lectures with didactic demos to understand the basic concepts

Video sequences to help for the resolution of basic exercices.

Practical work of increasing complexity requiring prior preparation for each session.
