A4-ft tall, 8-in wide concrete (150lb/ft3)
retainingwall is built. during a heavy rain, water fills the
spacebetween the wall and the earth behind it to a depth, h.
determine the maximum depth of water possible without the
walltipping over. the wall simply rests on the ground withoutbeing
anchored to it.
