The figure shows an angle frame with a fixed support at A. The height of the frame is 3a, while the width is 2a. A hinge is placed in the joint C and a bar element is connected to the two beam elements at B and D, respectively. A distributed transverse load with intensity p acts on the horizontal beam CE.
a) Determine the reaction components in A.
b) Determine the bar force NBD by placing a section through C and BD.
c) Determine the distribution of the internal forces N, Q and M.
d) Find the maximum moment Mmax
