How To Find The Resultant of Two Vectors:
Finding the resultant of two vectors is the same as finding the sum of the two vectors. Step 1: Find the horizontal (Fx) and vertical components (Fy) of each vector. F1x = F1Cos(angle) and F1y = F1Sin(angle) Step 2: Add the two horizontal vector components (Fx = F1x + F2x) and add the two vertical vector components (Fy = F1y + F2y) together. Step 3: Calculate the magnitude of the resultant force vector. F = SQRT[Fx^2 + Fy^2] Step 4: Calculate the reference angle of the resultant force vector which is the inverse tangent of Fy/Fx. Using the quadrant in which the force vector is located in, you can determine the angle of the force vector measured counterclockwise from the +x-axis. Quadrant 1: CCW Angle = Reference Angle Quadrant 2: CCW Angle = 180 - Reference Angle Quadrant 3: CCW Angle = 180 + Reference Angle Quadrant 4: CCW Angle = 360 - Reference Angle
