Red lines are axes.

There is a frictionless pin joint at point $$ that ic free to rotate about the y$-$axis.

Blue arrows show a distributed load along the rod from $B$ to $C.$ The rod $s$ from $B$ to $C$ is parallel to the $y-$axis.

Yellow dashed lines indicated length

FOR ALL FOLLOWING QUESTIONS, assume the following force vectors and moment arms for the system:

Red lines are axes.

There is a frictionless pin joint at point A that is free to rotate about the $y-$axis.

Blue arrows show a distributed load tha along the rod from $B$ to $C.$ The rod segn from $B$ to $C$ is parallel to the $y-$axis.

Yellow dashed lines indicated lengths.

The green line indicates a rope extendin $B$ to $E.$ The rope is fixed to the wall at $pc$

Draw the free$-$body diagram for the system. Be sure to draw and label all forces and geometry. Make sure to show the distributed force as a concentrated force at the appropriate location. Ensure your work is neat and legible.

Please paste a photo of your free body diagram in the answer box.
