## Homework Statement

in figure b , based on the direction of moment of anticlockwise is positive , i can say that -Tcos20 (7 sin 30 ) is a clockwise moment , so that the tension of rope should be acted in upward direction , so that the horizontal component of the force acted to the left to produce clockwise moment .

My question is why the author change to direction of tension or rope is acting downwards in figure c ?
