1. The problem statement, all variables and given/known data The concrete slab supports the six vertical loads shown. Determine the x- and y-coordinates of the point on the slab through with the resultant of the loading system passes. Image attached 2. Relevant equations 3. The attempt at a solution I started off by finding the resultant force. Seeing as how all the forces in the system act in only the z direction I summed them to get: Rz = 69Kn - 69kN -42kN - 44kN - 67kN - 59kN = -212 kN But I'm not sure how I should proceed from this step. I would appreciate any suggestions.
