Problem 2. Force \textbf{F} acts at corner E of
the rectangular plate. Hinges at A and
B and a roller beneath corner D
support the plate. Treat the hinges as
points along the x axis. Determine the
moment of force \textbf{F} about: (a) hinge A,
(b) hinge B, (c) the x-axis, (d) line DO,
(e) line AD, (f) line BD, and (g) line CD.
In determining the moment of force \textbf{F}
about lines, compute the magnitude
only.
\textbf{F} = (4\textbf{i} + 4\textbf{j} - 2\textbf{k})kN
