Q

Referring to “Wall Section A”, how many nails (and at what length) would you need to use at the connection between the 2X6’s and 2X8’s?

A

If we look at the drawing and check the sizes of framing members at each
location, we can see that the only place we have 2 X 6’s and 2 X 8’s together is
at the intersection between our rafters and our ceiling joists. Because we are
securing the rafters to joists, the edge can be considered as being supported.
Using the information we have gathered to navigate the nailing chat for framing
Table9.23.3.4, we can located the item that best identifies the location in
question:
Item 21 Rafter to joist(with idge supported):
Length of nail = 76mm
Minimum number of nails= 3

Q

Referring to “Wall Section A”, to what elevation would you excavate for your basement if the finished grade elevation is 729’ 3 5/8”?

A

height of our wall 7’4”), deduct the distance the wall projects above
finished grade 2”), and add the additional depth required for the
layer of gravel that is laid below the slab:
Depth of excavation = 7’4” - 2” + 4” = 7’6” = 7.5’
Next, you can either keep your measurements in feet and inches and
subtract them from your total:
729’3 5/8” - 7’6” = 728’15 5/8” - 7’6” = 721’9 5/8”
Or, you can also convert to decimal feet, subtract your distance and
convert back to feet, inches and fractions of an inch:
58 = 0.625” + 3” = 3.625” ÷ 12 inches/foot
= 0.3020833’ + 729’ = 729.30208333’
729.30208333’ - 7.5’ = 721.80208333’
721.80208333 - 721 = 0.80208333 X 12 = 9.625 - 9

= 0.625” X 16 = = 721’9 5/8”

1 Eave protection shall be laid beneath the stater stip and shall consist of,
(a) No. 15 asphalt-saturated felt laid in two plies lapped 480 mm and
cemented together with lap cement.

31
Q

. Referring to “Wall Section A”, the 10” thick drops are included for:

A

Looking at the section, we can see that the cantilevered section of the floor gets its structural support from being incorporated into the second floor framing. The support is provided by the full floor system and diagonal bracing is not required. We can also rule out the possibility of it being a tie in for the bricks, as it sits above the bricks and is tied into the wood sheathing that overlaps the bricks slightly. If you look at the brick section you can see that ties run from the sheathing behind the bricks through the veneer every 5th course.

32
Q

Referring to “Wall Section A”, what additional measures must be taken to provide adequate foundation drainage to the structure?

A

Answer: R22

34
Q

Referring to “Wall Section A”, what is the metric equivalent of your
ceiling joist dimension?

A

When 1”X8” bevel siding is applied to a building with 63/4” exposed to the weather, what height would be covered by 15 courses?

A

To calculate your distance of coverage, multiply your exposure per course by the number of courses, then convert back to inches and fractions of an inch:
6.75inches/course X 15 courses = 101.25” = 101 1/4”

56

A

slope of roof = south end elevation - north end elevation X 100 End to end distance
′
= (375.305’ - 269.488’)/185’ x 100

= 3.14%

65
Q

What is the area of the triangle?
Base = 219.9375’

66
Q

What is the length of the sides of an octagon whose overall width is
12’ 8

A

The easiest way to calculate the length of the sides of an octagon is to draw a square with four sides measuring the desired width of your structure,
calculating the hypotenuse and subtract the dimension of one side from the
hypotenuse dimension. The remainder will represent the length of each side:
√(12.66667′) + (12.66667 ) = = 17.9133765

Hypotenuse =
2 ′ √320.88905778ft²′

Length of sides = hypotenuse - desired width
= 17.9133765’ - 12.66667’
= 5.2467065’ ≈ 5’ 215⁄16”

67
Q

You are using a construction grout that cures at a rate of 0.0579inches/hour. How long will it take for a section that is 95/8” deep to cure?

A

First, convert the thickness into decimal inches:
5 ÷ 8 = 0.625” + 9” = 9.625”
Next, divide the thickness by the rate of cuing to get your answer in hours:
9.625” ÷ 0.0579inches/hour= 166.2348877 hours ≈ 166.235 hours
Finally, divide your hours by 24 to convert into days:
166.235hours ÷ 24hours/day = 6.9264583days ≈ 7days = 1 week

68
Q

An ellipse has a major axis of 175mm and a minor axis of 68mm. To replicate the same ellipse at a larger scale with a minor axis of 300m, what size will the major axis be?

A 
Convert all measurements into meters: 
Original ellipse: 
major axis = 175 mm ÷ 1,000mm/M= 0.175 m 
minor axis = 68mm ÷ 1,000mm/M= 0.068 m 
New large scale ellipse: 
major axis = x 
minor axis = 300 m 
Next, solve for x using ratio and proportion:

x
0.175m
=
300m 0.068m

0.175m × 300m
∴
x = = 772.0588m≈772m 0.068m

69
Q

How much concrete can be placed into a cylindrical form with a diameter of 28” and a height of 35’7 1/2”?

A

First, convert your dimensions into decimal feet:
diameter = 28” ÷ 12inches/foot = 2.33334 ‘
height = 7.5” ÷ 12inches/foot) + 35’ = 0.625’ + 35’ = 35.625’
Next, use your diameter to determine the circular area of the top of your fom:
use π = 3.1416
radius (r) = diameter ÷ 2 = 2.33334’ ÷ 2 = 1.16667’
area of circle = π² = 3.14161.16667’)² = 4.2760911 ft²

Q

A shed roof measuring 16’ X 28’ is covered with asphalt shingles. If the shingles weigh 235 lbs. per square, and the nails weigh 4.5 lbs. per square, what is the total weight of the shingle and nails you installed?

A

First, calculate the total area of your roof in square feet and divide your total by 100 1 square of shingles = 100 ft²):
roof area = 16’ X 28’ = 448 ft² ÷ 100ft²/square= 4.48 squares
Next, multiply the weight per square of your shingles by the number of squares, multiply the weight per square of your nails by the number of squares, and add your two weights to get your total material weight:
weight of shingles = 235lbs/square X 4.48 squares = 1,052.8 lbs.
weight of nails = 4.5lbs/square X 4.48 squares = 20.16 lbs.
total material weight = 1,052.8 lbs. + 20.16 lbs. = 1,072.96 lbs.
