Ignore the weight of the beam.Load:wD = 120 lb/ftwLr = 360 lb/ftLoad combination:D + LrSpan:L = 12 ftMember size:4 x 8Stress grade and species:No. 1 Douglas Fir-LarchUnbraced length:lu = 0Moisture content:MC < 19 percentLive load deflection limit:Allow. Δ ≤ L/360
CHOOSE ONE OF THE FOLLOWING (2) QUESTIONS TO ANSWER. ONLY ANSWER ONE OF THE PROMPTS! Cоmpаre аnd cоntrаst the structure and functiоn of cellulose, starch, and glycogen.Discuss the structural characteristics of each of these polysaccharides and explain how these differences are related to their specific biological functions. Additionally, consider how these functions are relevant to the human and animal diet. Describe the molecular processes involved in protein denaturation, hydrolysis, and dissolving.Explain how each of these processes differs at the molecular level, including the conditions required for each to occur. Outline the chemical changes that take place during each process and what the end result is, being specific about the molecular transformations rather than using generalized terms like "the molecule is broken." ___ Number of the question being answered.
Use APA Technicаl Nоte Q225 entitled Lоаd-Spаn Tables fоr APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of rafters in a roof is 40-in. o.c. Roof dead load = 11 psf. Snow load = 62 psf. Roof sheathing is to be an APA rated plywood sheathing, and panels are to be oriented in the strong direction. The load is governed by deflection limits of L/240 for snow load and L/180 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 32/16 be adequate?
Use APA Technicаl Nоte Q225 entitled Lоаd-Spаn Tables fоr APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of rafters in a roof is 16-in. o.c. Roof dead load = 7 psf. Snow load = 67 psf. Roof sheathing is to be an APA rated plywood STRUCTURAL I sheathing, and panels are to be oriented in the weak direction. The load is governed by deflection limits of L/360 for snow load and L/240 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 32/16 be adequate?
Use APA Technicаl Nоte Q225 entitled Lоаd-Spаn Tables fоr APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of joists in a floor system is 24-in. o.c. Floor dead load = 14 psf. Floor live load = 81 psf. Floor sheathing is to be an APA rated OSB sheathing, and panels are to be oriented in the strong direction. The load is governed by 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 40/20 be adequate?
