Un semáforo de 80N cuelga del punto medio de un cable de 30m tendido entre 2 postes. Halle la tensión en cada segmento del cable si éste tiene un pandeo que lo hace descender una distancia vertical de 1m

T1 = T2 = 602.33 N

Explanation:

I attached an image of the forces diagram below.

The x component of the forces for this cases is:

And the y components:

The angle is calculated by using the information about the length of the cable and the vertical distance of the traffic light:

Thus, you obtain:

hence, the tension in both segments of the cable is 602.33 N

f is prop to m1xm2 double m1 double force
