Part C

As shown, a load of magnitude $P$ is applied to a structure. Assuming that all members are weightless and that ABEF and $BCD$ are rigid bodies, find the magnitudes of the reactions at $D$ and $G$ needed to maintain the structure in equilibrium.

Assume the following values: $a=4\mathrm{.}50m,b=3\mathrm{.}00m,$ and $P=106N$
