FACSin 60=FABSin 30

FAB=3FACF_{AB}=\sqrt3F_{AC}

FACCos60+FABCos30+Mg=0F_{AC}Cos 60+F_{AB}Cos 30+Mg=0

FAC2+3FAC32+2009.81=0\frac{F_{AC}}{2}+\sqrt3F_{AC}\frac{\sqrt3}{2}+200*9.81=0

FAC=981NF_{AC}=-981N

FACCos30+T=0F_{AC}Cos30+T=0

T=FACCos30T=-F_{AC}Cos30

=(981)Cos30=-(-981)Cos30

=849.57N=849.57N
