A block hangs from the end of bar AB that is 5.80 meters
long and connected to the wall in the xz plane. The bar is
supported at end A by a ball joint such that it carries only a
compressive force along its axis. The bar is supported in
equilibrium at end B by cables BD and BC that connect to
the xz plane at points C and D respectively with
coordinates given in the figure. The z components of the
moments exerted on the bar by these two cables sum to 0.
The tension in cable BD is measured to be 210 Newtons.
Input answers of zero as 0.00 to avoid an invalid answer due
to significant figures.
Determine the equivalent force and couple system acting at
