A simple pendulum experiment is constructed from a point mass m attached to a pivot by a massless rod of length L in a constant gravitational field. The rod is released from an angle $\theta_0 < \pi/2$ at rest and the period of motion is found to be $T_0$. Ignore air resistance and friction.
What is the maximum value of the tension in the rod?

(A) mg
(B) 2mg
(C) $mL\theta_0/T_0^2$
(D) $mg \sin \theta_0$
(E) $mg(3 - 2 \cos \theta_0)$
