A geotechnical engineer is designing a retaining wall to hold back soil with a unit weight of 19 kN/m³. The wall will be 4 meters high, and the soil behind it will have a horizontal pressure of 28 kN/m². The engineer wants to use reinforced concrete with a density of 25 kN/m³. Determine the minimum required thickness of the wall if the engineer wants to limit the tensile stress in the concrete to 6 MPa.
