This is a good shear flow problem which basically comes down to effective calculation of the section parameter Q. Have a look and if you have a question or comment, post it here.

This module covers most of Chapter 8. The discussion of combined stresses is motivated by the relatively simpler problem of pressure vessels. We consider pressure vessels to have two normal stresses in two orthogonal directions, and we called these two stresses the hoop stress and the axial or longitudinal stress. We also […]

Once again I point you to this Flash module, which explains shear flow with some nice visualization and animation. It’s even got some narration. I strongly urge you to spend some time with this–it will really support your understanding of these problems.

Exam 2 will be held on Thursday April 5 at 7 pm in a room to be determined. This is based upon the MeetingWizard responses I received as of 3/26. This is also based upon alot of feedback about the ME students dynamics course, a differential equations exam, and some other exams.
The content […]

Last Friday in class, we looked at Problem 7-37 but didn’t quite finish. Several students have submitted their solutions to the problem, and you can see them here, here, here, or here.
Use this post as a way to “vote” on the best solution. Leave a comment and let everyone know which solution resonates […]

There are all problems about shear stress ans shear flow. Remember that the hardest part of all these problems is the calculation of the section parameter Q.
Shear stress: Probs. 7-4, 7-5, 7-11, 7-22, 7-25
Note that Problems 7-4 and 7-5 are sort of like two parts to the same problem
Shear Flow: 7-38, 7-47, 7-52.
Regarding […]

This module contains more detail on the calculation of the section property Q for transverse shear problems. I strongly recommend that you sit down and try to do some of these problems…alot of the confusion about the nature of Q and its calculation will be resolved once you just do some problems. As […]

This is a homework problem for tomorrow, and there has been enough confusion about the process that I just decided to post a video solution. Have a look and see if it helps your understanding of this type of problem.
There are a few important points to ponder as you listen to this solution:

We […]

This assignment is due on Friday March 23 at 4 pm in my office. All problems relate to unsymmetric bending or steel-reinforced concrete beams. Both of these topics involve some sort of material transformation according to the modulus ratio.
Probs. 6-123, 6-124, 6-126, 6-127
You will recognize that 6-123 and 6-127 are problems we discussed […]
