If the student chooses to approach the objectives with ‘Mechanical Engineering’ oriented materials
– 35.5 hours for a mechanical design project, through the study of a project in a small group, the students approach functional analysis, modelling (schematisation), the search for solutions, pre-dimensioning and the production of a ‘digital mock-up’ using CAD software. Students supplement the knowledge they need to develop the project with various documents at their disposal: resource documents on the ‘moodle’ platform, books, internet.
– 8 hours of practical work on bearing assembly,
– Using the elements made available to them (bearings, gear housing shafts, keys, elastic rings, locknuts, etc.), the students must analyse, design and produce bearing assemblies that comply with current regulations.
– 6 hours on the study and operation of different heat engines. Using visual aids, students discover the different cycles of internal combustion engines, the distribution and supply systems, and the principles of turbojet and turboprop engines. They identify the different functional elements of an engine from an overall drawing.
Materials for Mechanical Engineering – Lesson (7.5h)
– Phase transformations under equilibrium conditions: isothermal (eutectoid and eutectic) and non-isothermal transformations
– Diffusion: Fick’s laws (unidirectional)
– Germination-growth mechanisms of a new phase (from a liquid or a solid phase)
– Mechanical properties of metal alloys: fatigue strength and behaviour in the presence of cracks
TD topics (5h)

Objectifs
- Make the link between the mechanical, physical and chemical properties of construction materials (metals, ceramics and polymers) and the characteristics of these materials on an atomic (crystallographic) and microstructural (binary phase diagram) scale.
- Make a reasoned selection of metallic materials for mechanical construction by making the link between the mechanical characteristics and the nature of the metallic alloy: chemical composition, microstructure, nature of the phases, heat treatment possibilities, etc;
- Implement a design procedure based on specifications and acquire a technological culture.
The student may choose to approach this general objective with either a ‘Mechanical Engineering’ or a ‘Civil Engineering’ teaching aid.
If the student chooses to approach the objectives with ‘Mechanical Engineering’ oriented teaching aids, he/she must :
- Propose one or more solutions in the form of a kinematic diagram, based on a set of specifications.
- Calculate the powers involved and choose a motor.
- Design and size a simple gearbox.
- Design and size a radial contact ball bearing assembly.
- Calculate the isostatism of an assembly of fixed parts and a moving mechanism.
- Produce a digital model of the mechanism using CAD software.
- Give an oral and written presentation of the project.
- Participate and get involved in a work group.
- Identify the links to be implemented using real components for the bearings.
- Be familiar with 4-stroke and 2-stroke cycles.
- Be familiar with distribution and supply systems.
- Be familiar with the principles of turbojet and turboprop engines.
- Be able to identify the functional elements of an engine from a drawing.
- Be familiar with the secondary functions (cooling, lubrication, electrical generation, etc.).
- Be familiar with the terminology of the component parts.
If the student chooses to approach the objectives using ‘Civil Engineering’ oriented materials, he or she will be able to :
- Develop an interdisciplinary culture around sustainable urban development,
- To immerse themselves in the complexity of civil engineering design projects and in multi-criteria, multi-actor and multi-scale spatial and temporal decision-making.
- Discover the concepts of eco-design
- Design architectural programmes
- Define, select and specify construction materials
- Justify and assess the environmental impact of the solutions prescribed
- Design the load-bearing structure of buildings (vertical loads only)
- Calculating and predicting load transfer (gravity and operational loads only)
This course is designed to be closely linked to the development of skills in civil engineering project methods, the use of digital tools, the development of design project practices, the discovery of architectural design, the choice of construction techniques and materials and the use and development of multi-criteria and quantitative approaches.
The module provides an introduction to the dual Architect/Engineer curriculum, and develops analytical skills and design methods for building projects within an urban fabric. The project also provides an opportunity to practise the concepts of Resistance of Materials 2 seen in S4, with an understanding of beams, loads and the practical application of the principles of statics.
