Someone sent me an email:
are in the middle of studying and we were wondering if you could offer any kind of guidance towards what types of problems will be on the exam? We are looking at Chapter 13 material right now and there are so many different possibilities that it’s overwhelming. If you can help out at all..we would appreciate it!
So here goes:
This exam will primarily focus on the dynamics of particle motion, from Chapters 13 through 15. The material in Chapter 13, using linear momentum balance, is really important and we spent the most time in this chapter. The topics in Chapter 14, using work-energy, and Chapter 15, using impulse-momentum, were primarily used for specific cases. In the former we focused on conservative problems (total energy is constant) while in the latter we spent most of our time looking at impact (linear momentum is conserved).
There is definitely a lot of material, but what you need to make sure you have is an understanding of how to apply these methods. Remember the four steps that we apply when solving these problems (coordinates and directions, kinematics, free-body diagrams, eqns of motion).
