Question

A fish has been hooked and is pulling on the line as shown in the figure below. If the pole makes an angle of 25

A fish has been hooked and is pulling on the line as shown in the figure below. If the pole makes an angle of 25 degree with the horizontal, the distance between the point where the line is attached to the pole and the anglers hand is L = 2.45 m, and the fish pulls on the line such that the tension in the line is T = 114 N at an angle 35.0 degree below the horizontal, determine the magnitude of the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand. See if you can write an expression for the torque about the specified axis in terms of the tension in the line, magnitude of the displacement vector locating the point along the pole where the tension is applied and the angle between the direction of the displacement vector and the tension. N m

Explanation / Answer

T x L = |T| |L| sin60

= 2.45(114)(sin60)

= 241.88 Nm
