A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member FG if PB = 900 lb, PC = 2,400 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 adjusted bending strength, Fb’. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 1,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 6,000 lbPE = 7,000 lbQD = 3,000 lbQL = 3,500 lbQLr = 5,000 lbQS = 1,000 lbQR = 0 lbQW = 0 lbQE = 0 lbSpan:L = 13 ft Member size:4 x 14 Stress grade and species:No. 1 Douglas Fir-Larch Unbraced length:lu = 0 ft Moisture content:MC > 19 percent 

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 48/24 is used with framing that is spaced at 18 o.c. Does the panel require edge support? Assume the panel is 24 inches or wider.

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 40-in. o.c. Roof dead load = 5 psf. Snow load = 35 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 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 32-in. o.c. Roof dead load = 7 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?

A wood member is loaded as shown. Using ASD, determine the adjusted tension strength, Ft’. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 4,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 6,500 lbPE = 6,000 lbQD = 5,000 lbQL = 500 lbQLr = 3,000 lbQS = 2,000 lbQR = 3,000 lbQW = 0 lbQE = 0 lbSpan:L = 8 ft Member size:4 x 8 Stress grade and species:No. 2 Douglas Fir-Larch Unbraced length:lu = L/2 = 4 ft Moisture content:MC > 19 percent 

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member FG if PB = 800 lb, PC = 1,900 lb, PD = 3,200 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member FG if PB = 1,000 lb, PC = 1,800 lb, PD = 2,800 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

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 24-in. o.c. Floor dead load = 17 psf. Floor live load = 145 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?

A wood column is pin connected at its top and bottom. Determine the controlling slenderness ratio, le/d, for the column. Assume normal temperatures, no incising, and that all loads are downward. Ignore the weight of the member.Load:PD = 4,000 lbPL = 4,000 lbPLr = 1,500 lbPS = 3,000 lbPR = 2,000 lbPW = 3,500 lbPE = 0 lbLength:L = 11 ftMember size:4 x 10Stress grade and species:No. 2 Douglas Fir-LarchUnbraced length:lu = L = 11 ftMoisture content:MC < 19 percent
