• 2.0: Chapter 2 Video Introduction
Video introduction to the topics to be covered in this chapter: static equilibrium, equilibrium analysis of concurrent force systems, finding and calculating forces.
• 2.1: Static Equilibrium
Definition of static equilibrium, and its relation to force and acceleration, in terms of both linear and angular acceleration.
• 2.2: Point Forces as Vectors
Approximating surface forces as point forces. The line of action of forces. Representation of forces as vectors, magnitude-angle and component notations of vectors. Includes several worked example problems.
• 2.3: Principle of Transmissibility
The principle of transmissibility, and the situations where it can be applied to analysis of a rigid body vs. those where it cannot.
• 2.4: Concurrent Forces
The connection between lines of action and the concurrence of a set of point forces. Particle behavior of a body experiencing only concurrent forces.
• 2.5: Equilibrium Analysis for Concurrent Force Systems
How to solve problems involving analysis of concurrent forces on a body at static equilibrium. Includes several worked example problems.
• 2.6: Chapter 2 Homework Problems
