## Description

Teaching takes the form of two flipped classroom acquisition projects of the same size (RDM project, dynamics project). Students work in teams of 3 or 4. The resource course covers the following points:

- Dynamics :

- Fundamental principle of dynamics applied to the material point
- Geometry of masses
- Fundamental principle of the dynamics of material systems

- Strength of materials :

- Hooke's law - tensile test
- Cohesive force
- Concept of stress
- Stress matrix
- Study of simple stresses
- Tresca criterion

## Learning Outcomes AAv (AAv)

AAv1 [heures: 10,B3] : Correctly create the parameterisation to position a mechanical system at n ddl.

AAv2 [heures: 5,B3] : Correctly apply the integral calculations for each kinematic sub-assembly to the geometry of the masses.

AAv3 [heures: 10,B3] : Correctly apply the PFD methodology to the dynamic study of a system of solids.

AAv4 [heures: 5,B3] : Correctly analyse the equations from the PFD to size the actuators.

AAv5 [heures: 5,F2] : Correctly explain the team's work orally.

AAv6 [heures: 5,F2] : Correctly analyse your work in writing (activity report)

AAv7 [heures: 10,B3] : Correctly apply the PFS to determine the most stressed section of a beam.

- Correctly =
- All forces external to the beam are determined
- A cohesive torsor is calculated for each section
- The simple stress diagram is drawn, taking into account the shaft's peculiarities.
- The result is checked using RDM software.
- Interpretation of the diagram allows the most stressed section to be identified.

- Correctly =
AAv8 [heures: 8,B3] : Correctly establish a stress matrix at a point from the cohesion torsor.

AAv9 [heures: 5,B3] :Apply an imposed design criterion correctly
