Question

A block of mass m hangs from the end of bar AB that is
7.4 meters long and connected to the wall in the xz
plane. The bar is supported at A by a ball joint such that
it carries only a compressive force along its axis. The bar
is supported 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. Cable BD is elastic
and can be modeled as a linear spring with a spring
constant k = 550 N/m and unstretched length of 6.57
meters.
Determine the mass m, the compressive force in beam
