Two children hang by their hands from the same tree branch. The branch is straight, and grows from the tree trunk at an angle of 27 degrees above the horizontal. One child, with a mass of 39 kg is hanging 1.50 m along the branch from the tree trunk. The other child, with a mass of 29 kg, is hanging 2.10 m from the tree trunk. What is the magnitude of the net torque (in Nm) exerted on the branch by the children. Assume that the axis of rotation is located where branch joins the tree trunk and is perpendicular to the plane formed by the branch and trunk.
