Explanation:
In structural analysis, the conjugate beam method is often used to determine the bending moment and shear force in a beam. The conjugate beam is an imaginary beam with the same length as the real beam, but with the supports and loading conditions reversed.
When analyzing a real beam, we consider the supports to be fixed, hinged, or free. In the conjugate beam, the supports are reversed. So, if the real beam has a fixed support, the conjugate beam will have a free support, and vice versa. However, if the real beam has a hinged support, the conjugate beam will also have a hinged support. This is because a hinged support allows rotation, which is a characteristic of a hinged support in both the real and conjugate beams.
Key Points:
- The conjugate beam method is used to determine the bending moment and shear force in a beam.
- The conjugate beam has the same length as the real beam, but with reversed supports and loading conditions.
- In the conjugate beam, a fixed support in the real beam becomes a free support, and vice versa.
- However, a hinged support in the real beam remains a hinged support in the conjugate beam because it allows rotation.
