Free body diagram

I have problem on this question on how to draw free body diagram. Can you please show me on how to draw free body diagram on this question ?
The calculation part I think I do not have a problem with it.

Thank you in advance ! I am really struggle with this question.

I'd start with two FBDs. One for the pulley at B, and the other for the rigid frame that connects A-B-C.

Can you take a first cut at those two FBDs and then say what the next steps in the solution procedure would be?

I already did but I don't know that I am right or not

Use the "Attach files" link below the Edit window to upload PDF or JPEG images of your FBDs. If they are photographs of your work, please be sure they are clear and readable and rightside-up (no sideways images please). Thank you.

Remember that a CORRECT FBD includes ALL of the forces on the body. Omitting one or more forces is a very common error.

Welcome, jay_chay22!
Why are you struggling with this specific question?
Have you done other problems involving free body diagrams?

 

[Dr.D]

We still need to see 3 FBDs, one for the pulley and one for each link. Until that is done, there can be little help.
