1. The problem statement, all variables and given/known data I have four vectors arranged within a circle, with Vector A at 0 degrees with 1.47 N. Vector B is at 71 degree with 1.96 N. Vector C is at 152 degrees with 2.45 N. And Vector D is at 249 degree with 2.94 N. These vector are in Equilibrium. Calculate the resultant force in x and y components. This is a diagram of the Vectors 2. Relevant equations Well, I know that in equilibrium, the resultant force in the x and y component of the vectors is at ZERO. I know that Fx is Calculated by Fx = (Force)(Cos ANGLE) and Fy = (Force)(Sin ANGLE) What I need to find is the sum of all those vectors and have them as close as possible to zero, and find how much error there is. 3. The attempt at a solution Basically, I tried to sub all my numbers into Fx = (Force)(Cos Angle) to find the X- components. I found these numbers getting very weird.... And I am not sure after getting all these individual numbers whether to add them or to subtract them. This is the same problem I have with calculating the y-component. I am not sure if I am using the right angle...cause the only angles I am using in my equations are, 0, 71, 152, 249 degrees. And In the end, in finding the both x and y, would adding or would subtracting them be the way to find the resultant x & y? I know that it should be Zero.
