Statics/Three-Dimensional Equilibrium< Statics
There are six equations expressing the equilibrium of a rigid body in 3 dimensions.
Sum of Forces: , ,
Sum of Moments: , ,
To solve three dimensional statics problems:
- Resolve force components
- Resolve moments about a point
- Resolve moments about a line or axis. See Scalar Triple Product
Knowing how to find the Determinate of a matrix can help a lot here.
