A cylindrical rod of steel (E = 207 GPa, 30 * 106 psi) having a yield strength of 310 MPa (45,000 psi) is to be subjected to a l

sineoko [7]

Answer:9.477 mm

Step-by-step explanation:

Given

E=207 GPa

Yield Strength $(s_{yt}) 310 MPa$

load (P)=11,100 N

length of rod(L)=500 mm

$\Delta L=0.38 mm$

we know $\Delta L$ is given by

$\Delta =\frac{PL}{AE}$

where A= cross-section

$A=\frac{11100\times 500}{0.38\times 207\times 10^9}$

$A=70.556\times 10^{-6} m^2$

$A=\frac{\pi d^2}{2}=70.556\times 10^{-6} m^2$

$d=9.477\times 10^{-3} m$

d=9.477 mm

Identify BR rounded to the nearest tenth. HELP PLEASE!!

ahrayia [7]

Answer:

Step-by-step explanation:

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

We have

$adjacent=42\\hypotenuse=BR\\\alpha=31^o$

$\cos31^o\approx0.8572$

Substitute:

$\dfrac{42}{BR}=0.8572$

$\dfrac{42}{BR}=\dfrac{8,572}{10,000}$ <em>cross multiply</em>

$8,572BR=420,000$ <em>divide both sides by 8,572</em>

$BR=\dfrac{420,000}{8,572}$

$BR\approx49.0$

1. Enter the linear inequality shown in the graph.

Alborosie

Answer:

y=1/3x+2

Step-by-step explanation:

Find two points and find the x and y distance between them to get the slope. I did (0,2) and (6,0), and the distance between them was 2/6 which simplifies into 1/3.

Then (0,2) is the y-intercept because it's where the line crosses the y-intercept.

(hope this helps :P)
