A flying buttress transmits a load P = 25kN, acting at an angle of 60o to the horizontal, to the top of a vertical buttress AB (see figure). The vertical buttress has height h = 5.0m and rectangular cross section of thickness t = 1.5m and width b = 1.0m (perpendicular to the plane of the figure). The stone used in the construction weighs y = 26 kN/m3.
What is the required weight of the pedestal and statue above the vertical buttress (that is, above section A) to avoid any tensile stresses in the vertical buttress?
