-
B.
Unit method
-
C.
Flexibility method
-
D.
Force method
Correct Answer:
A. Displacement method
Explanation:
The moment distribution method is a structural analysis technique for statically indeterminate beams and frames, developed by Hardy Cross in 1930. It is classified as a displacement method because it focuses on joint rotations and displacements to determine internal moments. The process is iterative, involving the successive distribution of unbalanced moments at joints based on member stiffness and then carrying over a portion of those moments to adjacent joints until equilibrium is reached. It is also commonly referred to as the Hardy Cross method or simply the Cross method.
