A crate is hung by three ropes attached to a steel ring at A such that the top surface is parallel to the xy plane. Point A is located at a height of h = 83.82 cm above the top of the crate directly over the geometric center of the top surface. Use the given dimensions from the table below to perform the following calculations: a.) Determine the position vector b.) Compute the unit vector ûCA that points from point point A. c.) If rope AB carries a tension force of magnitude F = 674 → N, determine the force vector FT that expresses how this force acts on point A. 2013 Michael Swanbom cc i❀O BY NC SA Express each vector in Cartesian components to three significant figures. b PAD cm cm that describes rope AD ↑Z cm y Values for dimensions on the figure are given in the following table.
