The cable AB in Problem 2.97 exerts a 60-N force T on the collar at A that is directed along the line from A toward B. Express T in terms of components.
We know r_{BA} = 3.76i – 2.63j – 3k m from Problem 2.97. The unit vector u _{A B}=-r_{B A} /\left|r_{B A}\right|. The unit vector is u _{A B} = – 0.686i + 0.480j + 0.547k. Hence, the force vector T is given by
T =| T |(-0.686 i +0.480 j +0.547 k )~N =-41.1 i +28.8 j +32.8 k~N
