Checking the adequacy of a member of known size is considered _______.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 700 lb, PC = 2,100 lb, PD = 3,200 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

The density of a dried piece of 4×10 Hem-Fir dimension lumber that is 12 feet long and has a moisture content of 13% is _______.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 12.82 psf acts on the tributary area of one of the 50-ft girders, determine the equivalent distributed load that acts on the girder.

The two columns in the following floor framing plan support only loads from a bowling alley on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.7 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

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 = 1,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 7,500 lbPE = 5,000 lbQD = 1,500 lbQL = 3,500 lbQLr = 4,500 lbQS = 500 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 12 ft Member size:4 x 6 Stress grade and species:Select Structural Douglas Fir-Larch Unbraced length:lu = 0 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 = 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.

Determine the flat roof snow load, pf, for a building kept just above freezing with a roof that is fully exposed in terrain category C and has a risk category of I. Assume the ground snow load is 52 psf. Do not consider the minimum roof snow load, pm.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 700 lb, PC = 2,100 lb, PD = 3,200 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

The density of a dried piece of 4×10 Hem-Fir dimension lumber that is 12 feet long and has a moisture content of 13% is _______.
