Question

The figure below shows a person fishing with a fishing pole that makes an angle of 20.0° above the horizontal. The distance from the person's hand to the tip of the pole is

L = 2.04 m.

A fish is on the line, and it pulls the line with a force of

F = 115 N

at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an axis perpendicular to the page and passing through the person's hand?

A person fishing in a boat holding a fishing pole has a fish at the end of his line. The pole is of length L and he is holding it an angle of 20.0° above the horizontal. The fishing line, which extends from the end of the pole, makes an angle of 37.0° below the horizontal. A dotted line extends from the tip of the pole and makes an angle of 20.0° above the horizontal. An arrow labeled vector F points along the fishing line toward the fish.

______N · m

Answer 1

torque is given by

T = F r sin ( x +y)

T = 115* 2.04* sin ( 20 +37)

T = 196.752 Nm
