The Conjugate$-$Beam Method is a widely used technique in civil engineering to determine beam deflection. It involves treating the original beam as a different type of structure called the "conjugate beam." The conjugate beam has the same length as the original beam but has different properties. By analyzing the conjugate beam, engineers can calculate the deflection of the original beam.

In the Conjugate$-$Beam Method, the bending moment diagram of the original beam is converted into a shear force diagram for the conjugate beam. The deflection of the original beam at any point is then determined by analyzing the shear force distribution along the conjugate beam.

Objective Question: In the Conjugate$-$Beam Method, what is the relationship between the bending moment diagram of the original beam and the shear force diagram of the conjugate beam? A$)$ They are the same B$)$ They are inversely proportional C$)$ They are directly proportional D$)$ They are unrelated
