Homework Statement



Printed problem statement with a small diagram: a horizontal lever pivoted at A and held by a flat vertical bar with bearing B, free end loaded by vertical force F, with length a and dimension L marked.


I just don't understand how to set the problem for the free body diagram (point (a) and (b)). Can someone help me with this problem? Thank you in advance.
 
You're just replacing all the connecting pieces and supports with reaction forces. Give it a try.
 
My problem is, that I don't understand what keep the rigid lever and the flat bar together..
 
I would assume they are rigidly joined together.
 
Is it correct what I did till now?

Handwritten free-body diagram of an L-shaped member with vertical length L, horizontal arm of length a, force F at the end, and reactions Ax, Ay at top and B at bottom, with equilibrium equations written alongside.

Yes, looks good to me.

Technically there is supposed to be a vertical reaction at B also but that doesn't change your answer.
