... From the geometry of the problem, since the rope is at a 45° angle from the rod, in the coordinate system shown, Tx = −Ty The rod is in equilibrium, so the net torque on it is 0 about any point. I will take P as the center of torque for this calculation. Both the weight of the block and the tension ...
