The cables AB and AC are attached to the top of the transmission tower. The tension in cable AC is 8 kN. Determine the required tension T in cable AB such that the net effect of the two cable tensions is a downward force at point A. Determine the magnitude R of this downward force. $^e=k*-l *'51'3qo Tt =\T* [ (,i,$e. : *.osDr. c 9n'.L;'# =s3-61o = 4"q4J * 6.(6{ Af P = LF1uf ,",9^s + 6.e6 I o= GSr+ 6 (dj Tlu =l -itrl(- sin0lse*,o.
