A 4-ft-tall 8-in-wide concrete 150 lbft3 retaining wall is, Ask an Expert

Academics

A 4-ft-tall, 8-in.-wide concrete (150 lb/ft³) retaining wall is built as shown in Fig. P2.108. During a heavy rain, water fills the space between the wall and the earth behind it to a depth h. Determine the maximum depth of water possible without the wall tipping over. The wall simply rests on the ground without being anchored to it.
