What are the nominal dimensions for a 1x2 stick of lumber, a 2x4 stick of lumber and a standard sheet of plywood?

1 answer:

6 0

3/4 x 1 1/2 inches (19 x 38 mm) is the actual size for 1x2 stick of lumber,

1 1/2 x 3 1/2 inches (38 x 89 mm) is the actually size for a 2x4 stick of lumber,

Plywood is usually sold in 4 x 8-foot sheets. The most common nominal thicknesses of plywood are 1/2 inch and 3/4 inch, but once again the actual sizes are slightly different. A sheet of 1/2-inch plywood is really 15/32 inch thick, while a 3/4-inch sheet is 23/32 inch thick.

Hopefully this answers your question, I apologize if it doesn’t :)

Rashid [163]

Answer: the answer is plagiarism.

Explanation: Plagiarism is the act of taking credit from someone else's works or ideas, without acknowledging the author. Conflict of interest occurs when an employee has interests that are at odds to each other, which isn't shown at the excerpt given in the exercise. Fabrication is the creation of intellectual property, also not shown in the exercise, and falsification is the creation of a scientific hypothesis that cannot be verified by lack of practical evidence, which is not the case described as well.

Write this tension as a vector in both the cases.

Arte-miy333 [17]

The tension acting on point A is represented by the equation $\vec {T}_{A} = T_{AB}\cdot \left(-\frac{6.150}{10.483}\,\hat{i} - \frac{5.8}{10.483}\,\hat{j} + \frac{6.2}{10.483}\,\hat{k} \right)$ and the tension acting on point B is represented by the equation $\vec {T}_{B} = T_{AB}\cdot \left(\frac{6.150}{10.483}\,\hat{i} +\frac{5.8}{10.483}\,\hat{j} - \frac{6.2}{10.483}\,\hat{k} \right)$ .

<h3>How to express a tension in vector form</h3>

Vectors are numbers characterized by magnitude and direction. In this question we must represents a tension in the form of a vector. Please notice that tension is a reactive force caused by the action of an external force, often indirectly, in which the string is elongated.

The total length of the string is found by Pythagorean Theorem:

$l_{AB} = \sqrt{[2.5\,m +(5.8\,m)\cdot \sin 39^{\circ}]^{2}+(5.8\,m)^{2}+(6.2\,m)^{2}}$

$l_{AB} \approx 10.483\,m$

First, the tension acting on point A is:

$\vec {T}_{A} = T_{AB}\cdot \left(-\frac{6.150}{10.483}\,\hat{i} - \frac{5.8}{10.483}\,\hat{j} + \frac{6.2}{10.483}\,\hat{k} \right)$

Lastly, the tension acting on point B is:

$\vec {T}_{B} = T_{AB}\cdot \left(\frac{6.150}{10.483}\,\hat{i} +\frac{5.8}{10.483}\,\hat{j} - \frac{6.2}{10.483}\,\hat{k} \right)$

AysviL [449]

Answer:

41.6 A

Explanation:

Total power drawn = 1200 W + 1450 W + 1146 W + 1196 W = 4992 W

Power P = IV

I = P/V

Where I is the rms current,

V is the voltage = 120 V

I = 4992/120 = 41.6 A
