I owed you this one from last week. I did it this morning as a “cold one” (i.e., I didn’t work out the solution ahead of time) on the pulse pen. The problem is reasonably straight forward, and the only subtlety comes in when we consider the stress-based failure criterion. We consider […]

Whoa Nelly! You are not going to believe how good this solution is. There is a long interlude in the middle of this cold one where I try to figure out how I made a mistake (around 22:30 of the solution)…but I explain a couple of key things: (i) how did I know […]

Have a look […]

This is a problem from class on Friday 2/1. Not too difficult, but it is important to establish and then follow a clear procedure. I solved this as a cold one, but it went well because I was careful and orderly. You should strive for the same. As always, post your […]
