Awwwwww. A Valentine Treat for everyone. It’s new and improved and special! Now with ink and chapter markers! This module completes the discussion of angle of twist and introduces the notion of static indeterminacy in torsion, both of which are kind of important topics in torsion. Note that the last […]

In class on Monday, I was asked (twice) a good question about the nature of the twist angle derivation, specifically regarding the lengths of two legs of the “red” triangle. I actually dodged the question a bit, largely because I couldn’t think of a particularly good way to visualize the explanation. Last night, […]

You may recall that the first day of class, you took a few minutes to do a “concept review”–four questions which asked you to recall what you learned in statics. The point of this was two-fold: (i) it helps remind you of what’s important, and also highlights what you know and don’t know, and […]

I know…it’s like looking into the future. Somehow this lecture is posted to the web before it’s even been delivered. It’s kind of important–it introduces the notion of torsion and something called the torsion formula, which we will use repeatedly throughout the semester. The derivation of the relationship between the twist angle […]

If you were in class on Friday, you know that we covered this module in some detail, as well as one stress concentration problem. I think the general sense of the class is that stress concentrations are pretty easy to understand and apply, but I would encourage you to give this module a listen […]

Here it is, all about Ch. 4. This assignment is due on Friday 2/15 at NOON.
Probs.: 4-33, 4-45, 4-46, 4-56, 4-77, 4-89, 4-92
The first four are statically indeterminate and have some good statics content in them. The next one (3-77) is a thermal strain problem and is also statically indeterminate. The […]

So this module introduces the idea of static indeterminacy. Lots of real engineering structures are actually statically indeterminate, so it’s a good idea for you to understand both the physical and mathematical definitions. There’s also lots of information out there. Don’t believe me? Just Google it. In any case, this […]

This module is from Friday 2/1, and it introduces the basics of axial deformation on which we will build in subsequent lecture modules. The key here is the derivation of the (PL/AE) equation. Its usage is pretty straightforward, but will require you to practice, like, say, this.
