- 9.Modelled after problem 5 in the Problems_Torque_Statics: A 12.83-m-high and 19.48-m-long wall under construction and its bracing are shown in the figure. 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 871.28 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. The angle between the braces and the wall is as shown in the figure as 35 degrees.A seesaw consisting of a 1-kg board and length of 4 m balances Tony and Steve, as shown below.
