Torque Practice Test

A wrench turns a bolt about its center. A force $F$ is applied at the end of the wrench handle, but the force is directed along the handle toward the bolt, so the line of action passes through the pivot and the lever arm is $0$. What is the torque about the bolt?

A rigid rod is pivoted at its center. A force $F$ is applied at the right end at an oblique angle, closer to along the rod than perpendicular, so the line of action makes a small angle with the rod and the lever arm is small. Compared with applying the same $F$ perpendicular at the end, the torque magnitude is
