A bent tube is attached to a wall with brackets as shown. . A force of F = 980 lb is applied to the end of the tube with direction indicated by the dimensions in the figure. a.) Determine the force vector F in Cartesian components. b.) Resolve the force vector F into vector components parallel and perpendicular to the position vector rDA Express each of these vectors in Cartesian components. 2013 Michael Swanbom CC BY NC SA g →> h BB Z NE 8° A x F kaz с b Values for dimensions on the figure are given in the table below.
