Load is the load or weight the floor must support. Spacing
refers to the space between joists in inches. Span is the
length and/or width of supporting floor.
The load requirement in your plan is 60 psf at a joist spacing of 16 inches. If the room
dimensions are length 13 feet 2 inches and width 11 feet 7 inches, are 2×10 boards appropriate?
A. Yes, because 2 x 10 boards can support the width and length of the room
B. Yes, because 2 x 10 boards support the 70 psf
C. No, because 2 x 10 boards can support only the width of the room
D. No, because the 2 x 10 boards can support neither the width nor length of the room

Answer 1

The answer to the question is D. No, because the 2x10 boards can support neither the width nor length of the room.

option d is the correct

Step-by-step explanation:

The subject of this question is Engineering. The question asks whether 2x10 boards are appropriate for a load requirement in a room with specific dimensions. To determine this, we need to calculate if the 2x10 boards can support the load at the given joist spacing and room dimensions.

The load requirement is 60 psf at a joist spacing of 16 inches. The dimensions of the room are 13 feet 2 inches and 11 feet 7 inches. To calculate if the 2x10 boards are appropriate, we need to convert the dimensions to inches. 13 feet 2 inches is equal to 158 inches and 11 feet 7 inches is equal to 139 inches.

The total load that the 2x10 boards need to support is the product of the load requirement and the area of the room. In this case, the total load is (60 psf) * (158 inches * 139 inches) = 124,5480 pounds. Since 2x10 boards can typically support a load of 40 pounds per square foot, they are not appropriate for this load requirement. Therefore, the answer is D. No, because the 2x10 boards can support neither the width nor length of the room.
