  § 3.2  Cables, Bars, Springs Cables  (and wires and ropes) are  flexible  structural elements only capable of supporting  tensile  forces.   Bars  are rigid structural elements capable of supporting  tensile  or  compressive  forces. Cables We previously discussed cables wrapped around one or more pulleys.  We  said that, if we assumed the pulleys were  frictionless , each  single continuous cable  carried  a unique tensile force.  In some problems, there are multiple cables joined together at one  or more joints.  In these cases, we have to label a unique tensile force  for each cable  segment .

  The system shown consists of cables  AB  and  AC , horizontal cable  CE , and vertical bar  CD .  If the cables and bar have the failure  strengths shown, determine the largest load  P  that can be supported by the system.
