- The primary analysis method for these structures: disassembling them at the pins and drawing a Free Body Diagram for each component.

- How to apply Newton's Third Law at pin connections, where interaction forces between members are equal and opposite.

- The critical shortcut of identifying a two-force member to simplify the direction of unknown forces.

- A common exam trap: incorrectly assuming a member is a two-force member when an intermediate load is applied.
