Question

apply and analyze

1. give two reasons why carpenters install doors and windows with their tops at the same height.
2. what are two alternative methods to construct a header for large window openings without decreasing the length of the cripple studs?
3. why is a story pole often used when laying out wall framing?
4. after corner posts are plumb and top plates are doubled, how is a wall straightened?
5. what are four major benefits of advanced framing?
6. name two different uses for housewrap.
7. using 120 for the wall length, assume there are 6 corners, 5 intersections, 10 openings, and the framing is 24\ oc. find the number of studs needed, including outside walls and partitions.

Explanation:

Step1: Convert wall length to inches

The wall length is 120 feet. Since 1 foot = 12 inches, 120 feet = 120×12 = 1440 inches.

Step2: Calculate number of studs based on spacing

The framing is 24 - inches on - center (OC). The number of spaces between studs is $\frac{1440}{24}=60$. The number of studs for the length of the wall is 60 + 1=61.

Step3: Account for corners

Each corner typically has 2 or more studs. Assuming 2 studs per corner, for 6 corners, we add 6×2 - 6 = 6 additional studs (we subtract 6 because the corners are already partially counted in the length calculation).

Step4: Account for intersections

Assuming 2 additional studs per intersection, for 5 intersections, we add 5×2 = 10 studs.

Step5: Account for openings

Assuming 2 studs per opening, for 10 openings, we add 10×2 = 20 studs.

Step6: Calculate total number of studs

The total number of studs is 61+6 + 10+20=97.

Answer:

97
