3. Objective
Influence line of shear for determinate
structure : Determinate max/min shear
due to moving load.

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

5. 
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.

6. 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.
