Friction

Chapter 6 discusses friction, including its types and mechanisms, particularly focusing on dry friction. It presents various problems and sample calculations related to friction, such as determining the maximum angle of incline before slipping and calculating friction forces on a block under different applied forces. The chapter serves as a practical guide for understanding and solving friction-related problems in mechanical engineering.

Sample Problem 6-3

Determine the magnitude and


direction of the friction force
acting on the 100-kg block
shown if, first, P = 500 N and,
second, P = 100 N. µs = 0.20
and µk = 0.17. The forces are
applied with the block initially
at rest.
