2.001  Mechanics and Materials I

2.001 Final Exam

Dear Engineers,

Looking forward to seeing you tomorrow 1:30-4:30PM in the Johnson Ice Rink for the 2.001 final. The exam will consist of five question – less questions per unit time than previous exams! As previous exams, one question will involve hardware.

Best regards,
Tonio

2.001 Subject Evaluations

Engineers,

A kind reminder to please complete subject evaluations for 2.001:
http://web.mit.edu/subjectevaluation

Please complete the evals so future student generations can benefit, as you've benefitted from the subject evals completed by your upper-classmates.

MechE HQ takes these very seriously, when deciding what resources to allocate to future 2.001 classes. A high student response rate sends a message of student engagement. Please share with the department, what you thought of the hands-on exploratory learning modules, the professors & TAs, and course content – both the highlights and areas of improvement.

On behalf of the teaching crew, thank you. It's been a pleasure engaging with you this semester.

2.001 Final

Engineers:

Here are words of wisdom from years past, about preparing for the final:

(1) The material that is fair game on the final includes all material covered in class, PSets, and recitation, minus buckling.

(2) You will be allowed four (4) single-sided, 8.5"x11" pages of notes for the exam.

(3) You would be well-advised to be extremely comfortable with problems that involve combined loadings (e.g., pressure vessels + torsion, bending + axial loading, bending + torsion ... )

(4) The exam is challenging! So:
(a) Don't panic! We know that the exam is challenging and we will bear that in mind when we grade it.
(b) Use your time wisely! If you get stuck on a problem, move on and come back to it later. Do not let yourself get hung up on one question at the expense of the rest of the exam.

(5) We will be announcing extra office hours and review sessions shortly.
Happy studying and see you all on Wednesday (or sooner, if during review/office hours)!

Mohr's Circle Applets

Engineers,

Per popular request, here is a link to an applet that draws Mohr's circle in 2D and 3D. This may prove useful when double-checking your homework.

Stress Imaging!

Engineers,

During recitation this week, we'll be imaging stresses (ok - strains, to be precise) in transparent structures under various loading conditions, using the phenomenon of stress-induced birefringence, or photoelasticity.

1. We welcome your samples at lab – please bring flat, optically transparent, non-danegerous household objects to class tomorrow. Plastic and glass components are OK.
2. If you have a laptop computer, you may wish to bring it with battery fully charged.
3. If you have polarized sun glasses, please bring them to lab.
4. If you wear either glasses or contacts, you may want to wear contact lenses. But bring your glasses in a case (they're transparent and qualify as samples.

Looking forward to tomorrow,
Tonio
