A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member FG if PB = 900 lb, PC = 1,700 lb, PD = 3,100 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

A wood member is loaded as shown. Using ASD, determine the maximum bending stress in the member. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 3,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 6,000 lbPE = 6,500 lbQD = 1,500 lbQL = 2,500 lbQLr = 1,000 lbQS = 1,000 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 7 ft Member size:4 x 8 Stress grade and species:Select Structural Douglas Fir-Larch Unbraced length:lu = L/2 = 3.5 ft Moisture content:MC < 19 percent

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 12-in. o.c. Floor dead load = 14 psf. Floor live load = 65 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?

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 flat roof is 16-in. o.c. Roof dead load = 10 psf. Snow load = 36 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 the AWC Manual for Engineered Wood Construction, 2018 Edition to answer the following question. An APA Rated Sheathing panel with a span rating of 40/20 is used with framing that is spaced at 34 o.c. Does the panel require edge support? Assume the panel is 24 inches or wider.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A single-story wood-frame building is exposed to a wind load of wU = 350 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 68 ft, b = 22 ft, and the height of the walls be 9 ft. The walls are sheathed with blocked wood structural panels. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

A single-story wood-frame building is exposed to a wind load of wU = 220 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 44 ft, b = 30 ft, and the height of the walls be 10 ft. What is the unit shear in the shear walls?

Bolts should never be forcibly driven.
