Is the Free Body Diagram for C-Spanner Screw Failure Analysis Correct?

[victor198936]

Hi guys,

I'm working on one assignment about C-Spanner screw an impeller failure analysis. However, we're unsure if the free body diagram we draw is correct or not, given that our calculated safety factor is unreasonable.

Can anyone give us a hand and have a look. Moreover, if someone can provide the correct free body diagram, that would be much appreciate.

Regards,
