determine the total base shear $($the force trying to slide the house off the foundation$)$ when $($a$)$ the wind blows perpendicular to the long wall $($normal to the ridge$)$ vs$.$ when $($b$)$ the wind blows perpendicular to the narrow wall $($parallel to the ridge$).$ Also $($c$)$ determine the total overturning moment $($about the point where the bottom of the wall rests on the foundation at the lower right corner of the diagram$)$ caused by the wind blowing perpendicular to the long wall $($normal to the ridge$).[$Remember to consider the roof pressures in addition to the wall pressures when calculating the overturning moment.$]$ For this problem I recommend using the diagrams that show windward wall pressures as $$step functions.$$
