Draw and discuss the FBD for the following system. • Label all forces and directions. • How many unknowns are there? (Remember, an unknown does not have to be a force. It can also be a dimension, angle, etc.) • How many equilibrium equations can you create? • Is there enough information to solve for the unknowns? Explain.

Expert Solution
Step 1: Free-body diagram
The free-body diagram of the given problem is shown below and the major forces and dimensions also noted duly.
As seen from the free-body diagram, we have the only one unknown apart from the tensions in the cables.
i.e., The weight of the flower pot.
If we include the tensions of the cables we may need to find out TAB, TAC and TAD as they are also the unkowns.
The length of these cables are also should be considered as unkowns.
