A temporary excavation shown below is braced with a steel tube strut. Every morning, a misguided foreman tightens the screw mechanism on the strut "just to be safe". The stress on a soil particle at point A, just behind the wall, has been measured with pressure sensor installed by the Engineer. It now measures 40KPa. If the potential failure planes in the soil behind the wall sustain 60 degrees angles with respect to the vertical wall, determine the normal stress at point A along potential failure plane.
