The study of dynamic systems focuses on the behavior of physical systems as well as the physics of individual components and the interactions between them.  Control systems are designed to enable dynamic systems to respond in a specific manner.  In this course, we will learn about the mathematical modeling, analysis, and control of physical systems that are in rest, in motion, or acted upon by a force. Dynamic systems can be mechanical, electrical, thermal, hydraulic, pneumatic, or any combination thereof.  An electrical motor is a good example of a dynamic system in which electricity is used to drive the motor’s mechanical movement.  The operation of the motor is controlled by altering the electric current or voltage.  Another good example is a car’s suspension system, which is designed to curb abnormal vibrations while riding on a bumpy road.  In order to design a suspension system, you must analyze the mathematical equations of the physics of the suspension and its response (i.e. how effectivel…

Engineering design is the process of creating solutions to satisfy certain requirements given all the constraints.   This course will focus on the decision-making process that affects various stages of design, including resource allocation, scheduling, facilities management, material procurement, inspection, and quality control.  You will be introduced to the basic theoretical framework and several practical tools you can use to support decision making in the future.  The first two units provide an overview of engineering design process and theories and methods for making decisions, including Analytic Hierarchy Process, Lean Six Sigma, and Quality Function Deployment.  In Unit 3, you will learn about the basic principles of computerized decision support systems.  Unit 4 discusses several advanced mathematical methods used for support decision making, including linear and dynamic programming, decision tree, and Bayesian inference.

This course will ask you to apply the knowledge you have acquired over the course of the entire mechanical engineering curriculum.  It draws upon what you have learned in your courses in mechanics, CAD, materials and processing, thermal and fluid systems, and dynamics and control, just to name a few.  This course is equivalent to the capstone course or senior design project that you would need to complete as a senior in a mechanical engineering program in a traditional American university setting. This course begins in Unit 1 by introducing you to the stages of the design process.  We will then focus on tools and skill sets that are particularly important for succeeding in a design project, including design planning, teamwork skills, project management, and design reporting. Unit 2 covers important design principles and considerations.  You will learn about economic implications (you must keep cost in mind while designing!), the ethical, societal, and environmental impacts of design decisions, and pro…

This graduate-level course covers Lebesgue's integration theory with applications to analysis, including an introduction to convolution and the Fourier transform.

How can we know if the differences in wages between men and women are caused by discrimination or differences in background characteristics? In this course we look at causal effects as opposed to spurious relationships. We will discuss how they can be identified in the social sciences using quantitative data, and describe how this can help us understand social mechanisms.

Ce cours est une première introduction à la mécanique des fluides. Nous allons aborder tout d'abord les propriétés physiques des fluides : les états de la matière et la notion de viscosité. Un chapitre sera dédié à la tension de surface et à la capillarité. Nous introduirons ensuite le concept de similitude et l’utilisation des nombres adimensionnels. Nous allons alors considérer la statique des fluides à travers la loi de l'hydrostatique. La dynamique des fluides sera abordée en premier lieu par la cinématique. Ensuite, nous traiterons des équations de bilan avec notamment une application du théorème de conservation de l’énergie cinétique : le théorème de Bernoulli. Dans le dernier, nous montrerons que ce théorème relativement simple permet d’expliquer et de calculer des écoulements tels que ceux observés dans les rivières. Les vidéos du cours seront enrichies de vidéos d’expériences qui illustreront les concepts clés et par des quiz pour tester votre intuition et vos connaissances. Le dernier module vous permettra de piloter à distance une expérience d'hydraulique qui a lieu dans les laboratoires de l'EPFL.

This course is presented in French.

The course presents a systematic approach to design and assembly of mechanical assemblies, which should be of interest to engineering professionals, as well as post-baccalaureate students of mechanical, manufacturing and industrial engineering. It introduces mechanical and economic models of assemblies and assembly automation at two levels. "Assembly in the small" includes basic engineering models of part mating, and an explanation of the Remote Center Compliance. "Assembly in the large" takes a system view of assembly, including the notion of product architecture, feature-based design, and computer models of assemblies, analysis of mechanical constraint, assembly sequence analysis, tolerances, system-level design for assembly and JIT methods, and economics of assembly automation. Class exercises and homework include analyses of real assemblies, the mechanics of part mating, and a semester long project. Case studies and current research are included.

Here we will learn about the mechanical behavior of structures and materials, from the continuum description of properties to the atomistic and molecular mechanisms that confer those properties to all materials. We will cover elastic and plastic deformation, creep, and fracture of materials including crystalline and amorphous metals, ceramics, and (bio)polymers, and will focus on the design and processing of materials from the atomic to the macroscale to achieve desired mechanical behavior. Integrated laboratories provide the opportunity to explore these concepts through hands-on experiments including instrumentation of pressure vessels, visualization of atomistic deformation in bubble rafts, nanoindentation, and uniaxial mechanical testing, as well as writing assignments to communicate these findings to either general scientific or nontechnical audiences.

All around us, engineers are creating materials whose properties are exactly tailored to their purpose. This course is the first of three in a series of mechanics courses from the Department of Materials Science and Engineering at MIT. Taken together, these courses provide similar content to the MIT subject 3.032: Mechanical Behavior of Materials.

The 3.032x series provides an introduction to the mechanical behavior of materials, from both the continuum and atomistic points of view. At the continuum level, we learn how forces and displacements translate into stress and strain distributions within the material. At the atomistic level, we learn the mechanisms that control the mechanical properties of materials. Examples are drawn from metals, ceramics, glasses, polymers, biomaterials, composites and cellular materials.

Part 1 covers stress-strain behavior, topics in linear elasticity and the atomic basis for linear elasticity, and composite materials.

Part 2 ccovers stress transformations, beam bending, column buckling, and cellular materials.

Part 3 covers viscoelasticity (behavior intermediate to that of an elastic solid and that of a viscous fluid), plasticity (permanent deformation), creep in crystalline materials (time dependent behavior), brittle fracture (rapid crack propagation) and fatigue (failure due to repeated loading of a material).

This course is aimed at presenting the concepts underlying the response of polymeric materials to applied loads. These will include both the molecular mechanisms involved and the mathematical description of the relevant continuum mechanics. It is dominantly an "engineering" subject, but with an atomistic flavor. It covers the influence of processing and structure on mechanical properties of synthetic and natural polymers: Hookean and entropic elastic deformation, linear viscoelasticity, composite materials and laminates, yield and fracture.

This course introduces the fundamentals of machine tool and computer tool use. Students work with a variety of machine tools including the bandsaw, milling machine, and lathe. Instruction given on MATLAB®, MAPLE®, XESS™, and CAD. Emphasis is on problem solving, not programming or algorithmic development. Assignments are project-oriented relating to mechanical engineering topics. It is recommended that students take this subject in the first IAP after declaring the major in Mechanical Engineering.

This course was co-created by Prof. Douglas Hart and Dr. Kevin Otto.

12.524 is a survey of the mechanical behavior of rocks in natural geologic situations. Topics will include a brief survey of field evidence of rock deformation, physics of plastic deformation in minerals, brittle fracture and sliding, and pressure-solution processes. We will compare results of field petrologic and structural studies to data from experimental structural geology.

This course provides an introduction to the mechanics of solids with applications to science and engineering. We emphasize the three essential features of all mechanics analyses, namely: (a) the geometry of the motion and/or deformation of the structure, and conditions of geometric fit, (b) the forces on and within structures and assemblages; and (c) the physical aspects of the structural system (including material properties) which quantify relations between the forces and motions/deformation.
