A uniform rigid rod of mass M and length L is suspended by three massless strings, as shown in the following picture:
Two of the strings are at either ends of the rod. The third string is a length x from the left end. Find the tension in these three strings.
The Attempt at a Solution
Label the three tensions from left to right as T1, T2, and T3.
Since the net force is 0,
Since the net torque about the left end of the rod is 0,
I'm stuck from here; I need another equation in order to solve for the three tensions. I can't take torque about any other point because that will just give me an equivalent equation. What do I do?
