A $17\mathrm{.}0-$m$-$high and $11\mathrm{.}0-$m$-$long wall under construction and its bracing are shown in Figure $9\mathrm{.}30.$ The wall is in stable equilibrium without the bracing but can pivot at its base. Calculate the force exerted by each of the $10$ braces if a strong wind exerts a horizontal force of $650$ N on each square meter of the wall. Assume that the net force from the wind acts at a height halfway up the wall and that all braces exert equal forces parallel to their lengths. Neglect the thickness of the wall.
