(1) Write
the flexibility matrix corresponding to coordinates 1 and 2 for the structures
shown below.

(2) Use
the force method to find the bending moment at the intermediate supports of the
continuous beam shown in the figure.

(3) Use
the force method to find the bending moments at the supports of a continuous
beam on elastic (spring) supports. The beam has a constant flexural rigidity *EI*,
and the stiffness of the elastic supports is *K* = 20*EI/l*^{3}.
