These are both nice problems illustrating the details of the stress transformations on 3-D stress elements. There are some things to think about here (and Megan Turner and Jeff Jaekle have thought about them), especially concerning σ3. These are both nice and concise…enjoy!

This is good, good stuff. These guys (Jonathan Wenderoth, Mike McCormick, Chris Foley) worked and used Final Cut Pro at the DML. Hardcore video hacking! Final Cut is not for the faint of heart. Anyhow, they have done a nice job exploring something we didn’t touch on all that much in […]

This is the final bit of work on beam deflection for this semester: statically indeterminate beams. The thought processes are exactly like those we saw in earlier chapters (click on the embedded links), and probably the most expeditious way of doing this is using superposition. So, today’s module used the information in Appendix […]

Just stumbled upon another shear and moment resource on the web. This one appears to be pretty good because you can solve the problems on your own, then use their graphical flash-based diagram drawer to check your work.
If you are still struggling somewhat with V & M, this might be a really […]

Many thanks to Charles Shackelford and Chase Browning for supplying these two solutions. These are good problems from Chapter 9, and I urge you to use them as you prepare for the final.

Well, I’m not sure what the problem was, but I could not get the file exported in the usual format. Of all the times we’ve done this, this is the first time it actually hasn’t worked. Nonetheless, I spit out a Quicktime movie with the transitions and builds, but not audio . […]

Today we introduced beam deflections using the slope-displacement (integration) method. First, we looked at the fourth-order governing differential equation for the beam which relates (derivatives of) beam deflections to M(x), V(x), and -w(x). We also considered boundary conditions, which are the physically-relevant conditions allowing us to solve for the integration constants.
At the end […]

Sarah Ebmeier has generously provided a solution to Prob. 8-23, as well as another perspective on Prob. 9-45. We had two previous efforts on Prob. 9-45 as well.

I know many of you were taking notes (and at least one person was sleeping, you know who you are), but I’m feeling sort of charitable. So here are my notes. They are probably sort of worthless without the audio, but at least you have some record of today’s discussion. I was […]
