This online course from the MIT Department of Mechanical Engineering introduces principles of structural analysis and mechanics of materials for understanding and predicting material behavior under stress.

You will learn fundamental concepts of continuum mechanics, including internal resultants, displacement field, stress, and strain, with applications to three essential types of elastic load-bearing elements: bars in axial loading, axisymmetric shafts in torsion, and symmetric beams in bending.

While emphasizing analytical techniques, the course also introduces computing environments using MATLAB and numerical methods (Finite Elements).

This is the first course in a 3-part series which explores how mechanical engineers use analytical methods and calculations to predict structural behavior. The three courses in the series are:

  • Part 1 – 2.01x: Elements of Structures. Elastic response of Structural Elements: Bars, Shafts, Beams.
  • Part 2 – 2.02.1x Mechanics of Deformable Structures: Part 1. Assemblages of Elastic, Elastic-Plastic, and Viscoelastic Structural Elements.
  • Part 3 – 2.02.2x Mechanics of Deformable Structures: Part 2. Multi-axial Loading and Deformation. Energy Methods.
    Based on the first subject in solid mechanics for MIT Mechanical Engineering students, these undergraduate-level courses will teach you to rely on the notions of equilibrium, geometric compatibility, and constitutive material response to ensure that your structures will perform their specified mechanical functions without failing.

In this course, you will:

  • Use free body diagrams to formulate equilibrium equations
  • Identify geometric constraints to formulate compatibility equations
  • Understand the concepts of stress and strain at a material point.

For three fundamental types of slender structural elements (elastic bars, beams and shafts) you will learn:

  • To calculate internal stress and strain fields in the loaded elements
  • To predict the deformation in the loaded elements
  • To design structural elements so as to prevent failure
  • To use numerical methods (MATLAB) in structural engineering application

"This was an outstanding and truly enjoyable course...Didactic (and fun) video lessons; concise and clear board notes; problems and quizzes with outstanding (and very professionally presented) answer sections, which were very helpful to consolidate the acquired knowledge...Being a senior engineer who spent most of his career in management, it makes me really envious of the possibilities that current students, from all over the world, have to attend top classes as this one."

Q: I am a little rusty on my calculus skills and physics foundation; will I be able to succeed in this course?
A: Probably yes! During the first week we review all the concepts needed to understand the course material.

Q: Is this course similar to a residential course at MIT?
A: Yes, the three course series covers the same material taught in the MIT residential course 2.001: Mechanics and Materials I (the first core course in mechanical engineering typically taken the first semester of sophomore year)
