A mechanic uses a wrench of length \(r = 0.20 \text{ m}\) to tighten a bolt on a machine. The mechanic applies a force of varying magnitude at the very end of the wrench handle. The magnitude of the applied force \(F\) as a function of the angle \(\theta\) between the wrench handle and the force vector is shown in the graph.

What is the magnitude of the torque exerted on the bolt when the angle \(\theta\) is \(30^\circ\)?
