Please see attached document for full solutions.

1. Use the F.S. to figure out allowable F_BD.
F.S. = (ultimate load of F_BD)/(allowable load of F_BD)
Plug in: F.S. (3.2) and ultimate load.
Then, use algebra to solve for allowable load. (100kN).
Answer: 31.25kN

2. Use FBD to calculate P in terms of F_BD.
We can use forces ...
