14.2 Calculate the resultant of the two force vectors A and B acting at a point as shown in the diagram below. A 120 N 15° 8 80 N 20⁰ 14.3 If vector A were fixed, but the direction of vector B as well as the angle 8 between the vectors could be changed, for which value of 0 will the resultant force have the (i) maximum and (ii) minimum value? Determine this maximum and minimum value of the resultant force.
