This is a cold one, and even though the solution muddles about a little bit, it’s worth your time to stick with it. Especially through the part with the FBDs of each member of the structure. In particular, there are two important pieces of advice highlighted in this solution:
It’s useful to draw […]

This is the introduction to friction, and before the lecture today we did some small experiments. We introduced the notion of multi-valued STATIC friction, in which the sticking friction force assumes a value just large enough to ensure equilibrium–no more and no less. The video below illustrates this point using the classical inclined […]

At long last, here are the solutions to the exam problems. Just a reminder: average on the exam was about 86% and the grade distribution can be seen in this histogram. The point is that overall the class performance was quite good. But be warned: exam 2 will be more […]

One more cold one for you. As is apparent when you watch it, I did not solve this problem before actually sitting down to record the solution, so this is raw footage, the real deal. Not for the faint of heart. This was actually really interesting…there is a long, awkward, embarrassing pause […]

Oh boy. This one is from way back, probably two weeks ago and attached to Module 15 (and the problem session of Module 16). Anyhow, this is another in my string of experiments with “cold” problem solving. I had not thought about this problem at all when I sat down to make […]

We spent some time on Oct. 10 and 12 discussing trusses (and the exam), and we introduced a piece of software called Arcade. This is a really cool and powerful tool for structural analysis and visualization. As you saw in class, it has lots of great intuitive features (color and thickness of line, […]

As promised in class on Wednesday, here it is. A word of warning (and interest): I didn’t work out the solution ahead of time, so this is live real-time problem solving. As such, I make two mistakes in the solution which I take the time to correct. I guess there’s a […]

We started this problem with the ramp on Monday in class, and I sensed alot of confusion. I could tell because several people were giving me this kind of distant stare. In any case, I have written up the solution and recorded the video posted below. In it, I focus on the […]

Today we introduced Chapter 5 on rigid body equilibrium (you may find this useful as well?!?) and did some small examples. The think-pair-share approach is kind of a useful mechanism to get you talking specifically about the problem and asking yourself the hard questions about how to solve it. It’s something we’ll come […]

So this was my homework for today. I tried to capture alot of the discussion we had in class today as I describe the process of the solution. After the main part of the solution, I also introduce two other ways to solve for the location of the force resultant (both based upon […]
