The simply supported beam in Fig QB1a is made by gluing two pieces of wood
of rectangular cross-section as shown in Fig QB1b, i.e. the top board (flange) is
glued onto the bottom board of the web. The supports at A and B exert only
vertical reactions.

The built in supports prevent all lateral movements and rotations, but do not resist longitudinal movement. Beam (a) has a simple support at the right hand end which does not move vertically. The right hand support for beam (b) prevents a change of slope but does not exert a vertical force. Each beam is made from titanium, for which Young's modulus is 106GPa and the yield stress in 780MPa.
