Consider two vectors where F1 = 40 N, F2 = 57 N, and \theta _{1} = 240o and \theta _{2} = 25o, measured from the positive x-axis with counter-clockwise being positive. What is the magnitude of the equilibriant?

For the equilibrant, add the same vectors but with opposite directions (180 deg away), namely
theta_{1} = 60 deg and theta_{2} = 205 deg
456
