Statics- By Beer/ Johnston
Chapter 3- Rigid Bodies: Statics Equivalent Systems of Forces



 

In this chapter you will learn one of the most important concepts in statics and that is how to calculate moments. You actually already know how to do this on a simple scale because it was discussed in your physics class. Typically the first half of a physics class deals with statics and in that class you learned what a torque is, well that is exactly what a moment is. So let's get into this moment stuff a bit more!
