A branch of a tree grows out from the trunk at an angle of 24.0° above the horizontal. Two children hang by their hands from the branch of the tree. The first child has a mass of 44.5 kg and hangs 1.45 m from the tree trunk, as measured along the length of the branch. The second child, with a mass of 36.0 kg, hangs 1.80 m from the tree trunk, also measured along the branch. Determine the magnitude of the net torque exerted on the branch by the children, about an axis located where the branch joins the tree trunk and is perpendicular to the plane formed by the branch and the trunk. ???N · m

A crate sits on a wooden horizontal surface (a wooden floor). The figure shows a top view of this looking down onto the crate (gravity would be acting into the page). Man one and man two apply forces F1 and F2, at angles of θ1 and θ2 respectively, with the goal of moving the crate in the x-direction. A resultant force of Fr = 30.5 lbs in the x-direction is required to accomplish this. All of the forces are in the xy plane. If man one applies a force of F1 = 21 lbs at an angle of θ1 = 16° from the positive x-axis, complete the following steps to determine the magnitude and angle of the force man two must apply. c) Combine these two equations to develop an expression for tan(θ2) in terms of Fr, F1, F2, and θ1. Remember that the crate does not move along the y-direction. d)Solve numerically for the value of θ2 in degrees. e)Using this value for θ2 and other known values, solve numerically for the value of F2 in lbs.
