- 4.0: Video Introduction to Chapter 4
- Video introduction to the topics to be covered in this chapter: statically equivalent systems, and the relation between forces, moments and couples in such a system.
- 4.1: Statically Equivalent Systems
- Definition of statically equivalent systems. Outline of how to determine if sets of forces are statically equivalent, and how to convert multiple forces into a single statically equivalent force.
- 4.2: Resolution of a Force into a Force and a Couple
- The process for resolving a force applied at one point on a body into a force and a moment acting on another point, using the concept of couples. Includes several worked examples.
- 4.3: Equivalent Force Couple System
- Definition of an equivalent force couple system, and how to find it for a given set of forces and moments.
- 4.4: Distributed Forces
- Definition of distributed forces, and their classification as surface or body forces. Conventions for representing and analyzing distributed forces.
- 4.5: Equivalent Point Load
- Definition of the equivalent point force and methods of calculating it in two and three dimensions: integration; using the centroid or center of volume. Includes several worked samples.
