To reduce the vertical displacement of the roadway floor system of the arch produced by the 48-kip load at joint 18, diagonal cables of 2 in. in diameter are added as shown in Figure P6.34. For this configuration, determine the vertical displacement of all the floor system joints. Plotting to scale the vertical deflections of all joints along the roadway from joints 1 to 11. Properties of the diagonal cables are the same as those of the vertical cables.
