3: Static Equilibrium of Rigid Bodies
( \newcommand{\kernel}{\mathrm{null}\,}\)
- 3.1: Moment of a Force (Scalar)
- 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: 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.
