Problem

A student measures the torque produced by a single force of fixed magnitude on a pivoted rod as the angle

\theta

between the force and the rod is increased slowly from

0^\circ

180^\circ

. The data show that the torque is zero at

\theta = 0^\circ

and again at

\theta = 180^\circ

, while the maximum measured torque is

6.0\,\text{N}\cdot\text{m}

. At what angle does the maximum torque occur, and why does it peak there?
