1. What is true of the net force when 3 or more forces are in a state of equilibrium, explain.
2. If a force (F) make an angle (theta) with the x-axis, what are the formulas used to the x and y components of this force?
3. When finding the vector sum (resultant force) of two forces, does the orientation of the x-y axis have and effect on this vector sum? explain. (HInt: would the resultant foce and the direction of this force change if the x-y axis were rotatted one way or the other?)
