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.

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...

XERCISE 8.2 ties one end of a strong rope 8.00 m long to the bumper of his truck, 0 m from the ground, and the other end to a vertical tree trunk at a height A man 0.50 of 3.00 m. He uses the truck to create a tension of 8.00 102 N in the rope. Compute the magnitude of the torque on the tree due to the tension in the rope, with the base of the tree acting as...

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...

A m = 2.45 kg object hangs in equilibrium at the end of a rope (taken as massless) while a wind pushes the object with a F W = 15.7 N horizontal force. Find the magnitude of the tension in the rope and the rope's angle from the vertical. The acceleration due to gravity is g = 9.81 m/s2. A ball attached to the end of a rope hangs from an overhead support. The rope is straight, and hangs at...

A light rope is wrapped several times around a large wheel with a radius of 0.405 m . The wheel rotates in frictionless bearings about a stationary horizontal axis, as shown in the figure (Figure 1) . The free end of the rope is tied to a suitcase with a mass of 13.0 kg . The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.15 m/s when it...

An arrow is shot at an angle of ?=45? above the horizontal. The arrow hits a tree a horizontal distance D=220m away, at the same height above the ground as it was shot. Use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Suppose someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree. How long after the arrow was shot should the apple be dropped, in order...
