Question

1. in a multistory dwelling, joists are placed on top of the ______ along the headers.

a. ceiling
b. trusses
c. double plate
d. door framing

1. true or false? when trusses are used to form the roof frame, no additional ceiling frame is required.
2. a ______ must be included in the ceiling frame to provide an entrance to the attic area.

a. partition
b. header
c. scuttle
d. door frame

1. a strongback is used for all of the following, except ______.

a. strengthening a long span of ceiling joists
b. maintaining proper spacing between ceiling joists
c. keeping joists even along their lower edges
d. aligning the height of headers

1. when compared to a conventionally frame wall, the cost of building a house with sips is roughly ______.

a. double
b. half
c. the same
d. dependent on the size of the house

1. true or false? a house constructed with sips produces practically no waste during construction.
2. what is generally the first step in estimating wall and ceiling framing materials?

a. determine the amount of plates needed.
b. determine the number of studs required.
c. determine the total lineal feet of the walls.
d. determine the amount of header material required.

1. the amount of ceiling joists needed is estimated by the same method used for ______.

a. studs
b. floor joists
c. headers
d. wall sheathing

1. how many wall sheathing sheets are needed for a net area of 1460 sq. ft. and the selected sheets are 4×8?

a. 45 sheets.
b. 46 sheets.
c. 121 sheets.
d. 122 sheets.

Explanation:

1. In a multistory dwelling, joists are placed on top of the double - plate along the headers. So the answer is C.
2. True. When trusses are used to form the roof frame, they often serve as both the roof and ceiling support in some cases, so no additional ceiling frame is required.
3. A scuttle must be included in the ceiling frame to provide an entrance to the attic area. So the answer is C.
4. A strongback is used for strengthening a long span of ceiling joists, maintaining proper spacing between ceiling joists, and keeping joists even along their lower edges. It is not used for aligning the height of headers. So the answer is D.
5. The cost of building a house with SIPs (Structural Insulated Panels) is roughly the same as a conventionally framed wall. So the answer is C.
6. True. A house constructed with SIPs produces practically no waste during construction as they are pre - fabricated to specific sizes.
7. The first step in estimating wall and ceiling framing materials is to determine the total lineal feet of the walls. So the answer is C.
8. The amount of ceiling joists needed is estimated by the same method used for floor joists. So the answer is B.

Step1: Calculate the area of one sheet

The area of a sheet with dimensions $4'\times8'$ is $A = 4\times8=32$ square feet.

Step2: Calculate the number of sheets

The number of sheets $n=\frac{1460}{32}=45.625$. Since we can't have a fraction of a sheet, we need to round up to 46 sheets.

Answer:

B. 46 sheets
