Two children hang by their hands from the same tree branch. The branch is straight, and grows out from the tree at an angle of 33° above the horizontal. One child, with a mass of 31 kg, is 1.7 m along the branch from the tree trunk. The other child, with a mass of 32 kg, is 2.0 m along the branch 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
