Problem
Resolve the 1.5 kN force that acts from P(2 m, −1 m, 2 m) to Q(−1 m, 3 m, 0) into a component parallel to the line from R(0, 0, 0) to S(1 m, 1 m, 1 m) and a component perpendicular to that line. Report both component vectors and confirm that their vector sum equals the original force.
Hint
Write F along PQ, then project it onto the unit vector of RS.
