A moment is the turning effect of a force.
Moment = Force ×\times× Perpendicular Distance from pivot.
Clockwise moments are considered negative.
Force B acts into the pivot with no turning effect.
Equilibrium condition gives x=0.5x = 0.5x=0.5 m from B.
TC=(5/6)W+(100/3)T_C = (5/6)W + (100/3)TC=(5/6)W+(100/3) N.
TA=W/6−20/3T_A = W/6 - 20/3TA=W/6−20/3, where WWW is the total weight.
W=8TAW = 8T_AW=8TA based on tension conditions.
Identify the pivot point for moment calculations.
Sum of clockwise moments = sum of anticlockwise moments.
