A homeowner would like to improve the thermal resistance of their existing walls to reduce the heat loss in the winter. Which one of the following will most improve the home's thermal resistance?
Remove the existing fiberglass batt insulation and replace with 3.5 inches of foam filled urethane insulation with an R-Value of 6.2 per inch
Remove the existing wood bevel siding and replace with 1/2" thick stucco with an R-Value of 0.2
Add another layer of 1/2" gypsum wall board to the inside walls with a U-Value of 2.222
Remove the existing wood bevel siding and replace with 3-1/2" thick brick with an R-Value of 0.2, and 2" rigid board extruded polystyrene with an R-Value of 5.0
What is the maximum deflection of the steel beam represented by the beam diagram above if w1 = 1200 lb/ft, the moment of inertia of the beam is I = 475 in.4, and the modulus of elasticity of steel is 29,000,000 psi?
0.31 in.

Water, granules, sand, gravel
Granules, silt, clay, peat
Sand, silt, peat, clay
Gravel, sand, silt, clay
If the inside and outside air films are neglected, what is the R-value for the wall assembly shown in the diagram?
Which type of beam load is shown and what is the maximum shear force?
The beam is loaded with a uniform load, and the maximum shear force is (100 lbs/ft)(16 ft)/2 = 800 lb.
The beam is loaded with a uniform load, and the maximum shear force is (100 lbs/ft)(16 ft) = 1600 lb.
The beam is loaded with a concentrated load, and the maximum shear force is (1600 lbs/ft)/(8 ft) = 200 lb.
The beam is loaded with a concentrated load, and the maximum shear force is (1/2)(100 lb/ft)(8 ft) = 400 lb.
A low rise commercial building is to be built on a site where the footing will rest on a clayey gravel. Each column will carry a load of 27,000 lb. A table of soil bearing capacities is shown. Assume that concrete weighs 150 pounds per cubic foot.
Given that each concrete footing is 1’-6” thick, what are the plan dimensions for the most economical spread footing to safely support each column load?
3’-0” x 3’-0”
3’-2” x 3’-2”
3’-8” x 3’-8”
4’-8” x 4’-8”
