A uniform beam of arbitrary unsymmetrical cross section and length 2
L
is
built-in at one end and is simply supported in the vertical direction at a point half-
way along its length. This support, however, allows the beam to deflect freely in the
horizontal
z
direction (Fig. P.13.15). Determine the vertical reaction at the support.
