4:45 you said Ta is counterclockwise (+) but Tb clockwise (-). I’m confused because you drew them the exact same way and earlier in the video at 3:32 it was counterclockwise, equal and opposite

Torque is a type of moment, so I used the equation of equilibrium for a moment and got the same answers for your T at a and b, is this method also fundamentally correct?
