Homework Statement
This is a diagram from "Structural Analysis" by Aslam Kassimalli while solving frames using slope-deflection method. In the figure, the tangent to the deflected shape at C` is parallel to the original member AC implying that the slope at C is zero. However, later they have considered θC (the slope at C) as an unknown while writing the slope deflection equations. Why so?
