- 3.0: Video Introduction to Chapter 3
- Video introduction to the topics to be covered in this chapter: equilibrium analysis for extended rigid body systems, involving the calculation of moments.
- 3.1: Moment of a Force about a Point (Scalar Calculation)
- Further explanation of the moment of a force, and the equation for calculating a moment. How to calculate the moment using only scalar quantities, for two- and three-dimensional systems. Includes several worked examples.
- 3.2: Varignon's Theorem
- Using Varignon's Theorem as an alternative to finding perpendicular distances, in scalar moment calculations. Includes several worked examples.
- 3.3: Couples
- Definition of a force couple, and calculation of the moment produced by a couple.
- 3.4: Moment about a Point (Vector)
- Calculating the moment about a point by taking a vector cross product, with discussion of how to apply this method in both two- and three-dimensional problems. Includes several worked examples.
- 3.5: Moment of a Force About an Axis
- Calculating the moment a force exerts about an axis.
- 3.6: Equilibrium Analysis for a Rigid Body
- Using the definition of static equilibrium to set up equations that allow for the analysis of rigid body systems. Includes several worked examples.
