Answer 2

Answer:

The correct option is b) In the slope-deflection method, the joint rotations are taken as unknown.

Explanation:

• George A. Maney developed the slope deflection method in 1914 for the structural study of beams and frames.
• Before the moment distribution method was created, the slope deflection method was extensively used for more than a decade.
• Flexural deformations are taken into consideration by the approach, but axial and shear deformations are not.
• Rotations and relative joint displacements are thus the unknowns in the slope-deflection technique of analysis.
• This method necessitates the simultaneous solution of equations involving rotations, joint displacements, stiffness, and member lengths in order to get the end moments of the members at the joint.

The joint rotations are taken as unknown in the slope deflection method.
