The integrations needed to determine beam ... deflection at B and C is zero, as prescribed by the BCs. There are no constraints on the slopes of the displacements at B and C. The deflection at B and C ...
(Think a deck of playing cards.) Under the action of a transverse load we see below how the beam deflects in the absence of shear stiffness. Focus, in particular, on the deflection at the right end of ...
