Homework Statement
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.
Homework Equations
F=ma
Torque=I(alpha)
The Attempt at a Solution
Label the three tensions from left to right as T1, T2, and T3.
Since the net force is 0,
T1+T2+T3=Mg
Since the net torque about the left end of the rod is 0,
T2*x+T3*L=Mg*L/2
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?
