1. The problem statement, all variables and given/known data Find the magnitude and direction of a resultant force equivalent to the given force system and locate its point of application on the slab. 3. The attempt at a solution So I summed the forces to get -1400 N, or a 1400 N force downward (the book agrees with that). Why is the resultant force going upward? It seems to me that they have printed a 1400 N force upward. I have no issue with the rest of the problem, but was hoping someone could explain to me why Fr is going upward.
