Tension can support objects in surprising ways $($Google "tensegrity"$).$ In this problem, we have a simplified version of a tensegrity model, but it's actually also a simplified model of a specialized boom crane design. A horizontal uniform bar of mass m$1=85$ kg is suspended by a cable on the left side $($which exerts a downward tension TB$)$ and a cable a distance of d $=2\mathrm{.}2$ m towards the right $($which exerts an upward tension TA$).$ A mass of m$2=1100$ kg is located a distance of x $=4\mathrm{.}2$ m from the left side. The bar is L$=5\mathrm{.}8$ m long.

Part a$/$ What is the tension in cable A$?$

Part b$.$ What is the tension in cable b$?$
