A crate is hung by three ropes attached to a steel ring at A such that the top surface is parallel to the zy
plane. Point A is located at a height of h = 111.76 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 TAD that describes rope AD.
b.) Compute the unit vector to that points from point C to point A.
c.) If rope AB carries a tension force of magnitude P= 776 N, determine the force vector F that
expresses how this force acts on point A.
Express each vector in Cartesian components to three significant figures.
