A 30 kg buzzard is sitting on a cable. The cable is attached to two poles 25
meters a part; the bird is sitting 6 meters from one end and the cable sags two
meters. Find the cable tension on each side of the bird.

Respuesta :

Answer:

T1 = 675 [N] ; T2 = 707.5 [N]

Explanation:

To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.

In the attached image we can see the free body diagram with different forces, angles and distances.

By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.

Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)
