The torque on the torsion pendulum produced by forces acting on two test bodies is: t = r 1 x f 1 + r 2 x f 2 the fiber must hang along the vector f 1 + f 2otherwise, the net force on the pendulum could not be zero, and it could never be at restthe component of the torque parallel to the fiber will twist the fiber.
