The structure which can be completely analyzed by static equilibrium equation are called determinate structure.
Determinate structure :

Definition : An influence line is a plot of the magnitude of the resulting reaction/axial force/shear/moment generated in a beam or structure as a unit load travels across its length. Influence lines can be generated for any of these actions (reactions, axial forces, shears, or moments) in a structure.
Introduction to Influence Lines
![Page 6: Influence line of shear for determinate structure : Determinate max/min shear due to moving load](https://reader035.fdocuments.net/reader035/viewer/2022062405/557838b0d8b42a1f5b8b48dc/html5/thumbnails/6.jpg)
Influence lines are used to determine where to place moving loads on a structure to obtain maximum results (reactions, shears, moments, axial forces), and to compute these reactions or other actions (shears/moments/axial forces) once the loads are placed in critical positions.
