One method of determining the value of
w
n
is to take moments at the centerline of the
beam (knowing the moment there is
M
n
at collapse). Reference is made here to Figure
14.11(a) for the beam reactions.

The same value could be obtained by considering the diagrams shown in Figure
14.12. You will remember that a fixed-end beam can be replaced with a simply supported
