The following roofing materials are stacked on a pallet at a construction site. The pallet is 4 ft by 7 ft, and the materials have been cut and stacked so that each layer completely covers the pallet. Use ASCE 7-10 to determine the total dead load resting on the pallet.4 layers of asphalt shingles5 layers of decking, 2-in. wood (Douglas fir)6 layers of plywood, 1/2-in. thick

Use APA Technical Note Q225 entitled Load-Span Tables for APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of joists in a floor system is 19.2-in. o.c. Floor dead load = 20 psf. Floor live load = 121 psf. Floor sheathing is to be an APA rated OSB Sturd-I-Floor sheathing, and panels are to be oriented in the strong direction. The load is governed by a deflection limit of L/240, bending, and shear for total load. Only consider these limits. Assume multi-span, normal duration of load, dry conditions, and panels 24 inches or wider. Would a panel with a span rating of 24 oc be adequate?
