A long retaining wall is braced by wood shores set at an angle of 30° and supported by concrete thrust blocks, as shown in the first part of the figure. The shores are evenly spaced at 3 m apart. Soil Retaining wall Concrete Shore thrust block 30 ¹0.5 m k 4.0m For analysis purposes, the wall and shores are idealized as shown in the second part of the figure. Note that the base of the wall and both ends of the shores a e assumed to be pinned. The pressure of the soil against the wall is assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the walls is If each shore has a 137 mm x 137 mm square cross section, what is the compressive stress in the shores (in MPa)? (Enter the magnitude.) MPa

For analysis purposes, the wall and shores are idealized as shown in the second part of the figure. Note that the base of the wall and both ends of the shores are assumed to be pinned. The pressure of the soil against the wall is assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the walls is
F = 206 kN.
If each shore has a 137 mm x 137 mm square cross section, what is the compressive stress in the shores (in MPa)? (Enter the magnitude.)
