Project “Designing a Mechanical Structure”
Within the project, students
  • Design a mechanical structure, recognize and implement different phases within such a process: problem formulation; analyzing and establishing design requirements; introducing concept designs; choosing a concept; detailing the design of choice; assigning materials. 
  • Evaluate different concept designs, choose a concept and justify their choice.
  • Apply their earlier knowledge on material science and production techniques from previous modules in the current design project.
  • Apply the knowledge gained from “Mechanics of Materials” and “Modeling and Programming” courses on detail design of the chosen concept.
  • Utilize stress and strain transformations (using e.g. Mohr’s circle) to calculate principal stresses and strains and apply it in the project.

Academic Skills
  • Write a (design-) report for the client.
  • Being able to reflect on your own work as a mechanical engineering student and future professional.

This quartile consists of a project assignment and five courses:
Project “Designing a Mechanical Structure”
The aim of the project is to design a functional structure which allows students to integrate their various mechanical design skills. The theoretical knowledge gained by the students during the current module and earlier courses such as Mechanics of materials, Material science, Statics and Machine elements are applied in the project. The project includes designing mechanical components, proper choice of materials and suitable production methods. The assignment is done within groups of 8 students. The subject of the project varies each year, however in principal the project characteristics (structure composed of a number of moving parts) remain the same. The structure is usually made of slender elements (pipes and profiles) with a functional purpose. The project is limited to the conceptual phase and mainly focuses on realizing feasibility and the development of the concept product.
Linear Algebra
In this course of Linear Algebra we mainly focus on systems of linear equations (linear systems). Many real life situations can be modeled as a linear system. Examples are networks (traffic networks, data networks, electrical networks, etc.), economic models, chemical reactions, cryptography (coding of messages), scheduling, computer graphics, GPS.
Linear Algebra starts with an introduction of linear systems which will be described using a (coefficient-) matrix. Already in the first week we learn how to solve linear systems systematically, using a row reduction technique on the coefficient matrix. In the second week we focus on operations vectors and matrices, such as addition, multiplication, inverse and transpose. These operations are a fundamental issue in Linear Algebra. In the third week we deal with sets of vectors with very nice properties: subspaces. It turns out than the properties of subspaces can tell us a lot about the structure of solution sets of linear systems. Here the concepts of linear combination, linear independence, basis and dimension play an important role. In the fourth week we introduce the concept of determinant of a square matrix. We explore its properties and show some interesting interpretations. The fifth week will be about eigenvectors and eigenvalues of a square matrix. These concepts play a crucial role in discrete dynamic systems, which arise in many scientific fields. Finally, in the last week, we examine linear transformations and their properties. Some well-known applications in geometry will be treated as well. Much emphasis is laid on the relations among the various concepts. A case-study will be implemented in each program, to become acquainted with applications of Linear Algebra.

Mechanics of Materials
This course covers how the stiffness and strength of a structure consisting of different members such as bars, beams and shafts can be determined. Stiffness describes the relationship between loads and deflections of a structure and strength refers to stresses and strains occurring in the material.
Modeling and Programming
The Finite Element Method is a key engineering tool for the design of mechanical systems. It can be used to determine internal stresses and deformation of structures due to external loads. A basic form of the Finite Element Method for beam structures will be developed throughout a series of ModPro 4 sessions. The complexity of the systems will gradually increase during the sessions, from 1D truss systems, to single beam calculations, to full truss and beam structures. Optimization methods discussed in ModPro 3 will be used to optimize structure designs.

Machine Elements
This course offers an introduction into mechanical engineering design, in which basic mechanical engineering functions and concepts are discussed systematically. Engineering concepts and design principles are provided to select and design machine elements that are commonly found in mechanical systems and constructions. The relation between function, material, connection method, shape, size and cost of machine elements is discussed in relation to systems specifications. Practical design principles for combining stresses and different types of loading are analyzed. The design of a complete mechanical power transmission system is covered including belt and chain drives, gears, shafts, keys, couplings, seals and bearings. The design of standardized machine elements for connections are discussed including fasteners, springs, machine frames, bolted connections and welded joints.

Academic Skills
In this final module of the year, various aspects of academic skills are addressed; communication in writing, oral presentation and being able to reflect on your own work.
The results of the project have to be presented in a written (design-) report for the client and an oral presentation for a committee.
In an individual assignment the student has to reflect on his own work in the last year and look forward to the future as a student (and professional) in mechanical engineering
