A long retaining wall is braced by wood shores set at an angleof 30 degrees and supported by concrete thrust blocks The shores are evenly spaced

A long retaining wall is braced by wood shores set at an angleof 30 degrees and supported by concrete thrust blocks.Theshores are evenly spaced 3 m apart.For analysis purpose, the wall and shoresare idealizied.The base of the wall and both ends ofthe shores are assumed to be pinned. Thepressure of the soilagainst the wall is assumed to be triangularly distributed, and theresultant force acting on a 3-meter length of the wall isF=190kN.If the shore has a 150mm X 150mm squarecross section, what is the compressive stress σc inthe shores?I know the right answer is 5.21 MPa from the back of the book,I am just having problems getting there.
