A newly planted tree is supported against the wind by a rope tied to a stake in the ground, as shown in the figure below. The force of the wind, though distributed over the tree, is equivalent to a single force F, as shown in the figure. Find the tension in the rope. Assume that neither the tree's weight nor the force of the ground on the tree's roots produces any significant torque about point O. (Let F = 117 N, D = 2.06 m and d = 1.40 m.) angle: 37 degrees
Homework Answers
considering equilibrium of torque about root
117 * 2.06 = T sin 37* 1.4
T = 286.06 N

Comment in case any doubt, will reply for sure.. Goodluck

A support rope is tied to a tree at a height of 8.6 m above the ground. With a wind blowing from the left, the magnitude of the tension required in the rope to keep the tree stationary is 2.80*102 N, and the torque about point P due to the tension has a magnitude of 1.80*103N.m. Determine the angle between the rope and the tree trunk.
