search keyword : " 80 W sin 13 = 40 W l sin 13 + 7 Fj cos 45 "

look at the picture above the keyword you just searched for..

i don't understand why you would add 7 Fj cos45 to the torque equation. I thought we only consider the forces perpendicular to the 'lever arm'. The Fj is on the pivot, so shouldn't we not take Fj into consideration for the torque equation? thanks
