Answer:
The width of member is as follows:
b = 3 ft
b = 3 × 12 in.
b= 36 in.
The depth of member is as follows:
d = 8 ft
d = 8 × 12 in.
d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d
A= (36 - 7/8) × 96
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A
P = 1000 x 3372
P = 3372000 lbs
P = 3372 kips
The surface area of the larger solid, rounded to the nearest hundredth is given by: Option B:
Volume of a solid is usually expressed in cubic units, or units cube.
Suppose that the volume was expressed in x cubic units. Then you can say that the considered solid takes same space as the volume occupied by x cubes of 1 unit as their side lengths.
<h3>What are similar objects?</h3>They're like zoomed version of each other(might be non-zoomed, zoomed in, or zoomed out). Their sides can be obtained by multiplying one object's sides by a single constant(by single constant, we mean constant which will be same for obtaining any corresponding side).
For the given case, we're given that:
Both solids are similar.
Thus, let the scale factor by which their sides change be 'f'.
Then, we get:
(as two times sides multiplied, so two times f got multiplied).
Similarly,
Or
As surface area of smaller solid(second solid is smaller as its volume is less) is 74.32 sq. inches, and f = 1.8, thus, we get:
Thus, the surface area of the larger solid, rounded to the nearest hundredth is given by: Option B:
