Step 2

Calculation:

Draw free body diagram for the given diagram. Then we can able to find the load directions and forces.

If we observe the figure the block was fixed to the wall. There will be two cases in the moment for block from the back support. That will be upward and downward.

So, we can draw the FBD for two cases.
