Wine barrels are often stacked in this particular form. If we seek to describe the forces acting on a particular wine barrel in the middle they take the form of 5 vectors. In this case the vectors have a certain symmetry and we will define the x direction as horizontal and the y direction as vertical. For the purposes of this discussion we will assume that one of the vectors is F_g = -2.104 N j, and the two lower force vectors (one pushing up from the lower left and one pushing up from the lower right) both have the form F_L = ± 4.104 N i + 4.104 N j where the first term is + or - depending on which side it's on. Since these 3 vectors, along with two symmetric vectors on the top (at the same angles downward), must all add up to 0 what are the components of the two vectors acting on the top of the barrel?
