The Quonset hut is subjected to a horizontal wind, and the pressure p against the circular roof is approximated by p0 cos θ. The pressure is positive on the windward side of the hut and is negative on the leeward side. Determine the total horizontal shear force Q on the foundation per unit length of roof measured normal to the paper.
