What is the equation that results from choosing the pivot point to be the point from which the mass hangs (where W acts)? Express your answer in terms of the unknown quantities T_L and T_R and the known lengths x and L. Recall that counterclockwise torque is positive.
____
can anyone please give me hints as to how to start this? I know that sum of net external forces in this picture is 0 so sum of forces in the y direction is T_L +T_R - W = 0 and .. i also know that sum of external forces and torque = 0 ...
