23. The free-body diagrams for block Band for the knot just above block Aare shown next.GT1is the tension force of the rope pulling on block Bor pulling on the knot (as the case may be), GT2is the tension force exerted by the second rope (at angle θ= 30°) on the knot,Gfis the force of static friction exerted by the horizontal surface on block B,NFGis normal force exerted by the surface on block B,WAis the weight of block A(WAis the magnitude of mgAG), and WBis the weight of block B(WB= 711 N is the magnitude of
