The Facts
We had a small discussion in class the other day about the graphical method for shear and moment diagram construction. In particular, we had some difficulty with determining whether a particular quadratic-or-higher-order curve was concave up or concave down. For instance, we had a case of a linear shear, and the question […]

This is a good one. Bending deformation, curvature, stress, etc. can be quite confusing, so I strongly encourage you to download and review this module at least once. When combined with the description in the book, this module should give you a good picture of how we derive the flexure formula.

Homework 5 is due on Monday Feb. 26 at 4 pm in my office. The assignment is:
5-80, 5-87, 5-116, 6-9, 6-15, 6-21, 6-39
For the shear and moment problems, use whatever method you like (equations or graphical). Just remember, this is review material from statics, so I expect perfect V&M diagrams regardless of your […]

Today we reviewed some concepts on shear and moment, but we also introduced the so-called graphical approach to V & M. It’s a very useful and powerful approach that requires lots of practice to master. However, once you master it, the graphical approach gives you a great deal of speed and flexibility for […]

Thursday at 7 pm! Based upon your votes (64 total), 45 said that Thursday 7-9 works. So let’s do it.
The exam will cover Chapters 1-4, including everything we covered in class. We will EXCLUDE thermal stress from the exam. Everything else is fair game.
Exam problems will be very much like the […]

There were no prepared notes on Wednesday, but I hope the problem session on Chapter 5 was useful to everyone. I certainly would welcome any solutions you wish to submit to any of the problems we did (5-111, 5-76, 5-61). In particular, 5-61 has been discussed on the homework thread as well, so […]

Based upon the limited input I received (11 comments on the blog, 1 email–that’s less than 15% of the class), it looks like the consensus is Wednesday night. The only concern is a possible conflict with one or two other review sessions. We will start NEXT WEEK (2/21) and see how it works. […]

Homeworks 1 and 2 are now in the folders outside my office. Please drop by and pick up your graded work. I will be assembling PDFs of the solutions and emailing them to you this week. Of interest:

Homework 1 average: about 18/20 across both sections
Homework 2 average: about […]
