The light red rod with two 90° bends as shown is pinned at
(a, 0, 0) and (0, b, c) and can rotate freely. A weight W is
suspended at mid‐span of the horizontal element as shown.
A rope T attached at C in anchored in the XZ plane to keep
the system in equilibrium. Determine the coordinates of this
anchor point so that the rope force T is a minimum. What is
the minimum rope force?
