(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 = 20EI/l3.
