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 […]

Here is a solution from Bobby Arthur from Wednesday’s class. It’s a very clear solution using the integral equations to find the equivalent force and moment for the distributed load. Kudos to Bobby for some nice, clear work!

A student in class suggested we could use the blog as a way to spontanteously self-assemble study groups for working on homework or preparing for an exam. I told him I would put something up on the blog, so here it is…the Instant Study Group category.
The idea is simple. Regardless of the time […]

Luke Waidmann offers this solution to the problems we discussed the other day in class. These are a good complement to my partial video solution from a few days ago. This gives you a good feel for the vector and scalar methods for 2-D problems, so have a look and decide which approach […]

The class has spoken! Exam 1 is going to be on Wednesday October 10, from 7-9 pm in a location to be determined. This is certainly not going to meet everyone’s needs, so if you have a HARD conflict, please let me know ASAP and we will schedule a different time for you.
Some […]

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 […]

This is actually, truth be told, a partial solution to the problem. But it illustrates the use of the integral equations in determining both the resultant force and its location for a uniformly distributed load. You will in the future be able to do the uniform (and even linear) load distributions without much […]

So at the end of lecture today, we discussed two ways of doing moment-type problems: the “vector” way and the “scalar” way. In addition to the information embedded in the lecture, I have also put together a small video showing how to do part of Prob. 4-102 using both approaches. Both the […]

Here it is, late but better than never. This was a sort-of brief module which expanded our understanding of moments and couples, and allowed us to do some problems in class. We will continue this discussion in Module 12 (Sept. 24). The main take-away from this module is the different between a […]
