Question

A tree contractor has been hired by a homeowner to remove a damaged tree from a previous storm. The top of the tree broke off leaving the trunk left in the ground. The two arborists will remove the tree by attaching a rope near the top and cutting the base close to the ground. The scenario is shown in the figure below. If the arborist pulls on the rope with a force of magnitude F = 38.5 N calculate the components of the torque τ with respect to the base P of the tree. The distances in the figure are: d = 14.7 m, h = 1.45 m, s = 5.66 m and r = 11.96 m.
