HigherEd 2.0

As we decided in class on Friday, Exam One will be on Thursday 10/2 from 6.30-8.30 in room E303 Thornton Hall. The exam will cover Chapters 1-4, and you can bring 1 sheet of 8.5 x 11 paper with writing on ONE SIDE only. Bring your calculator, a pencil, an eraser. During […]

Here we consider force and moment equivalence in the context of distributed loads. I have written the equations slightly differently here than I did in lecture, so if you took good notes in class you now have to slightly different views of the process. In the end, the key point is that the […]

Another classic! This lecture deals with equivalence, but first it introduces the notion of moment calculations and specifically couple moments. There is a derivation right in the middle on why the couple moment is independent of the point around which we calculate it (hint: it’s only a function of the relative position […]

This is a good one about the scalar triple product. Especially the last two or three slides. The main point is that the dot product and cross product can work together as a fairly powerful team to get you the information you need about moment action around a particular axis. Enjoy.

This is from Wed. 9/3. We cover dot products and some particle equilibrium. By far the most important thing we discussed is something not recorded here: how to construct good FBDs. We will certainly review this again on Friday, but it’s worth your time to consider the last few minutes of […]

Today we looked at some vector mechanics, and probably the most important concept to come out of today is this: each component of the vector has a very specific physical meaning…a meaning which gives you clues about how to check your work. The two problem we did in class both had some built-in […]
