i figured out the second one

The first one Homework Statement Consider the bar to have negligible mass. How far from point 'A' must a downward force of 40.5 N be applied in order to achieve rotational equilibrium. Homework Equations T1=T2 F=0 The Attempt at a Solution 5x9.8x2.1 + 3.5x9.8x4.3 + 40.5xd = 0 d=6.18m
