Force A$=5000$N Force B$=500$N Force D$=1000$N angle $40$ degrees Distances OA$=600$mm OB$=800$mm OC$=1200$mm OD$=1600$mm $2.$ A beam carries loads as shown below.

a$)$ Draw a free body diagram of the beam by itself. Make sure you show $...$

$-$ the coordinate system and $(+)$ directions for forces and moments,

$-...$ make sure you show me all applied forces AND all reaction forces and moments $($if any$)$ that can act through these supports,

$-$ For any forces applied at an angle, also show the force components in x and $\backslash ($ y $\backslash ),$ and

$-$ Show any other information that belongs on a free body diagram. $(20$ points$)$

b$)$ Find the reaction forces at the supports. $(40$ points$)$
