1. The problem statement, all variables and given/known data Given: AD=DC = 9m P=78kN S=25Kn Angle alpha = 35 deg A is static but B is movable I need to solve forces on the bases A and B I do not understand where do I mark the forces if there is a base that can move. 2. Relevant equations 3. The attempt at a solution My attempt: I am not sure whether there should be Bx or Ax.
