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 $0\mathrm{.}9$Kg$/$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.
