Station 5
At station 5, there was a ring with a weight of 10N of force being pulled down from it. A 25 degree angle was being made with the spring scale (which measures 8N) and the ring. The tension force of the other string was unknown. To find this force, we drew a diagram in which all the vectors were placed together from start to finish. The displacement or resultant vector of this diagram represented the tension force of the string, and we figured out that this force equalled 10N.

We know that the net force is zero so the vectors must begin and end at the same point.by drawing these forces head to tail we ca figure out the missing force with a resultant vector
