As promised in class, here it is. The important part of the problem is to first manipulate the equations (stress, strain, etc.) into that one single equation–which shows up in bright green in this video. Enjoy!

On Friday 1/25 we had two problems that we discussed in class but didn’t solve. I am delighted to report that I received multiple efforts from students, and the first two correct, neat solutions I received are posted below.

(Note: in 1-61, the term “double shear” is explained on page 33, and is essentially the same as […]

I recorded this earlier this morning, and it basically reflects everything we discussed in class yesterday. In particular, I tried to tidy up the discussion of complementary shear stress to make it more clear and concise. I would also encourage you to read the text materials on shear stress, and you might even […]

Not much of a welcome, I guess. We’re going to have a good semester, have some fun, and learn alot about strength of materials. But first, let’s start with a quick refresher on statics. These three problems are all from the 7th edition of Hibbeler, Chapter 1.

As usual, use this […]
