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

I REALLY NEED HELP FOR THIS ONE

Natasha2012 [34]

Answer:

Step-by-step explanation:

Area of shaded region it is area of hexagon minus area of circle.

A regular hexagon is comprised of six equilateral triangles (of the same sides).

So its area: $A_1=6\cdot\dfrac{S^2\sqrt3}{4}=\dfrac{3S^2\sqrt3}2$ {S = side of the triangle}

Height (H) of such a triangle is equal to radius (R) of a circle inscribed in the hexagon:

$R = H = \dfrac{S\sqrt3}{2}$

Area of shaded region:

$A=A_1-A_\circ=\dfrac{3S^2\sqrt3}2-\pi R^2=\dfrac{6S^2\sqrt3}4-\pi\left(\dfrac{S\sqrt3}2\right)^2=\dfrac{S^2(6\sqrt3-3\pi)}4$

S = 6 cm

so:

$A=\dfrac{6^2(6\sqrt3-3\pi)}4=\dfrac{36(6\sqrt3-3\pi)}4=9(6\sqrt3-3\pi)=27(2\sqrt3-\pi)\ cm^2\\\\A=27(2\sqrt3-\pi)\ cm^2\approx8.71\ cm^2$
