Given the force vector FCD = -2/-2J- 2 k lb applied at the point C where the position of point C with respect to point A IS TAC = 3 /- 1J-1 k In. and a line through the two points A = ( -1. -3, 0) and B = (-2. 1, 2) as shown determine the projection of the moment onto the Ine. - - a) Calculate the cross product MA = TAC X FCD J- k Ib.In. bj Calculate a unit length vector directed from point A to Point B. c) Calculate the projection of the moment vector onto the line. MAB = Ib.In. of Write the projected moment In full component form. MAB = 1 1-1 k lb.In.
