Equations: Net torque=0=Net force
I believe this is a static equilibrium question but cant figure out how to do it
ah got it thank youYou get involved with the forces along the line of the 80Kg rod, that's not what you should do, the x-axis is not the line of the 80Kg rod, the first picture at OP shows which are the x -axis and the y-axis.
In the y-axis you got the weights of the rod and the mass m, 80Kg and 10Kg respectively (and the F_y component of the force from wall at A).
In the x-axis you got F_x and the tension T from the cable.
