Q$2)[7$ points$]$ An overhead lines, the line is supported from two towers their heights are $40$m and $32$ m above the ground level. The conductor's weight is $0\mathrm{.}9K\frac{g}{m}$ and the tension in the conductor is $35$ KN $.$ if the distance between the clearance point and the lowest tower$($ x $1)$ is $120$ m $,$ then calculate :

i$.$ Span between the two towers.

$2.$ clearance between the lowest point and the ground level.
