Question: A fiber optic cable is suspended over the poles so that the angle at the supports is . Determine the minimum tension in the cable

A fiber optic cable is suspended over the poles so that the angle at the supports is θ. Determine the minimum tension in the cable and the sag. The cable has a mass density ρ and the supports are at the same elevation.

Given:

θ = 22 deg

ρ = 0.9kg/m

a = 30 m

g = 9.81m/s2
