What force will exert on the rope poplar?
Tamar wants to cut down a tree, poplar great dead with his chainsaw, but it does not fall on the nearby gazebo. Yoojin helps with a long rope. Yoojin, a physicist, suggests that they attach the rope stretched from the poplar tree oak, then pull the rope on the side (Figure below). If the rope is 40.0 m long and Yoojin pulls on the side in the middle of the rope with a force of 360.0 N, causing a lateral shift of 2.00 m of rope at mid-term review, which will force the rope exert on the poplar? [Hint: Until poplar cut is enough to start falling, the rope is in equilibrium.] show all work
The cord is forming a triangle with 40m ISOCELE basic and 2m high. This triangle is decomposed into 2 with the right side 20 m and 2m. Hypotenuse is sqrt (20 ^ 2 + 2 ^ 2) = 20.1 m the point of traction tension of 360N is balanced by two voltage vectors equal each oriented tree. The sum of these vectors is 360N. These vectors drag the hypotenuse the triangle and their magnitude are propotional half the ratio of hypotenuse to move without comment. n = 1 / 2 * 20.1m/2m * 360m = 1609 NT
