B 3 m 4 m 20 a) The circular bar has a 4-m radius and lies in the x-y plane. Express the position vector from point B to the collar at A in terms of components. b) The cable AB 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. 4 m B 3 m 4 m 20 a) The circular bar has a 4-m radius and lies in the x-y plane.
