A man ties one end of a strong rope 9.18 m long to the bumper of his truck, 0.561 m from the ground, and the other end to a vertical tree trunk at a height of 3.30 m. He uses the truck to create a tension of 8.17 102 N in the rope. Compute the magnitude of the torque on the tree due to the tension in the rope, with the base of the tree acting as the reference point. N · m
a.) A tension force, T, of magnitude 5.0 N is applied to the end of a bar at a distance r = 1.5 m from the axis of rotation O (represented by the black dot). The angle between the force and the distance vector, θ=25o. Calculate the magnitude and direction of the torque vector. b.) In the previous problem, let’s make some changes. The bar is now a different length and reoriented within 3-D space such that the r is a vector that has components (3,2,0) in the xyz coordinate frame, and F is a vector with components (4,5,0). What is the torque exerted on the rigid body about a pivot located at the origin? Express your answer in i, j, k, components. Assume all distances are represented in meters and forces in newtons.
A fisherman is fishing with a 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 = 1.85 m. A fish is on the line, and it pulls the line with a force of F = 116 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?
One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts at a 36.1o angle with respect to the length of the stick. Where along the stick is the 6.00-N force applied? Express this distance with respect to the end of the stick that is pinned.
Two children hang by their hands from the same tree branch. The branch is straight, and grows out from the tree trunk at an angle of 27.0° above the horizontal. One child, with a mass of 41.0 kg, is hanging 1.05 m along the branch from the tree trunk. The other child, with a mass of 31.0 kg, is hanging 2.35 m from the tree trunk. What is the magnitude of the net torque exerted on the branch by the children? Assume that the axis is located where the branch joins the tree trunk and is perpendicular to the plane formed by the branch and the trunk.

The distance from the fisherman's hand to the tip of the pole is L = 2.14 m. A fish is on the line, and it pulls the line with a force of F = 116 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 fisherman's hand? A fisherman 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.
