Chapter 10, Problem 22P

The fishing pole in Figure P10.22 makes an angle of 20.0° with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the angler’s hand if the fish pulls on the fishing line with a force $\stackrel{\to }{F}=100\text{N}$ at an angle 37.0° below the horizontal? The force is applied at a point 2.00 m from the angler’s hands.
