Question: A 17.0-m-high and 11.0-m-long wall and its bracing under construction are shown in the figure.
Calculate the force, in newtons, exerted by each of the 10 braces if a strong wind exerts a horizontal force of 640 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.
