1. The problem statement, all variables and given/known data A 135 N vertical force P is applied to A to the bracket shown, which is held by screws at B and C. (a) Replace P with an equivalent force couple system at B. (b) Find the two horizontal forces at B and C that are equivalent to the couple obtained in part a. 2. Relevant equations 3. The attempt at a solution Well, I tried to find the moment of force P about the hinge and then match that moment with an opposite one by a force at point B...but I really don't know what I'm doing.
