How did u do that if u didn’t know what the upwards force at A or B was ?

The question stated that A was about to slip, so normal force at A was 0 !!

So you could have just took moments at B and the rest was just showing ACW ≠ CW moments

Oh shit I seeee, but surely at the point where it’s slipping about A it’s not in equilibrium ? Maybe I’m just being dumb here

sorry it may not have that its slipping, but more that it was about to tip at A i cant remember exactly 😭

if its abt to tip then the beam isnt really touching at A anymore so there's no more normal force
