An inclined suspended wooden bridge in a playground

Fig. 14-9: An inclinly suspended wooden bridge in a playground

As demonstrated in Section 14.3.3, an inclined suspended system moves sideway if a vertical load is applied asymmetrically. The phenomenon should be avoided in engineering structures, as it may lead to unsafe structures. However, Fig. 14-9 shows an outward inclinely suspended wood footbridge in a playground. The bridge is purposely built in such a way so that the bridge wobbles when a child walks on the bridge, creating excitement and a challenge for crossing the bridge.
