The maximum snow load on roof D is nearly

  When subjected to wind perpendicular to the ridge, the windward roof is subjected to a pressure of -13.3 psf and the leeward roof is subjected to a pressure of -9.9 psf.  Assume both of these pressures are uniform over the entire length of building (60 ft).  For an interior truss, the value of P3 is nearly

The series of buildings shown below are located in an area with ground snow load of 30 psf.  The upper roof (labelled B) has a slippery surface.  Assume Ct = Ce = Is= 1.0 for all the roofs.    The balanced snow load for roof B is nearly

The value of sliding snow load on roof D is nearly

The unbalanced snow load on windward side of roof B is nearly
