(delete were it says 345g at angle 245) after we place both of the weights, then we had to
find the angle and how much weight we need in order for the ring in the middle to center
itself and find the equilibrium. Once we find the angle and the weight that we need in
order to have it equilibrium, we change the second string at angle 120˚ and not change
the mass. Again we had to find the angle and how much mass we had to add on the third
string in order for it to be equilibrium. For the third run, we had to draw out a
quadrilateral were the vectors, if added up would make it equilibrium. When making the
quadrilateral we had to make it to scale and the lengths of the sides would equal a certain
mass. We later tested out drawing on the force table to make sure that it did work and that
it was an equilibrium vectors.
