Chapter 24. Incorporating Friction into Your Applications
When you think of friction, perhaps you think of the heat that's generated when you rub your hands together on a cold morning, or the scrapes and burns on your knees when you trip and fall over your dog on the way to the refrigerator in the middle of the night. Although these examples can be correctly called friction, in statics it has a slightly different meaning.
As you read through this chapter, you may realize that its contents are significantly different from the other chapters in Part VI of this text. In the other chapters of this part, I neglect the effects of friction on the problems in order to better explain the various techniques used to solve statics problems. However, in the real world, friction is an ever-present force that you must account for in all your calculations, so this chapter shows you how to do just that.
In this chapter, I describe the different types of friction and how to calculate their magnitudes, and then incorporate these values on a free-body diagram (F.B.D. — see Chapter 14). I also explore how the different objects in statics are affected by the various forms of friction.
