Draw Influence line diagram

Question

Accepted Answer

An influence line diagram shows the variation of a response function at a specific point due to a unit load moving along the structure.

Influence lines are used to determine the maximum or minimum response of a structure.
They are commonly used in civil engineering for designing bridges and other structures.
The diagram is drawn by considering the structure as a series of beams and calculating the deflection or reaction at the point of interest for a unit load at different positions along the structure.
The resulting diagram shows the variation of the response function at the point of interest as the unit load moves along the structure.
Influence lines can be used to determine the maximum bending moment, shear force, or deflection at a specific point due to a moving load.
The diagram can also be used to determine the position of the load that will cause the maximum response at the point of interest.
