I'm asked to find the W and I was told that the rope at C is in tension , there is reaction at B , my question is , is there any reaction at C ?
i have tried to do in this way , but i do not get the ans
vertical force = 80+10RB+TCRC2W=0 equation 1
total moment about A = 80(1) +10(3)+W(2)(5) = 0
110+10W= 2RB , RB= (110+10W) / 2 equation 2
total moment about B = 80(1)2TC +2RC +10(1) +W(2)(3) =0
TCRC = (6W70) / 2 equation 3
Sub equation 2 and 3 into 1 ,
i gt 90(110+10W) / 2 + (6W70) / 2 2W = 0
i gt 18W= 0
why cant i do int his way ?
