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

Solve the equation below for x: <br><br> logx+log(x-2)=log(3x)

Ugo [173]

Answer:

x=5

Step-by-step explanation:

Given equation is

$\log\left(x\right)+\log(x-2)=\log(3x)$

Apply formula: $\log A+\log B=\log\left(AB\right)$

$\log\left(x(x-2)\right)=\log(3x)$

$\log\left(x^2-2x)\right)=\log(3x)$

Since both sides have equal bases so we can drop the log

$x^2-2x=3x$

$x^2-2x-3x=0$

$x^2-5x=0$

$x(x-5)=0$

Which gives x=0 and x-5=0

or x=0 and x=5

Original problem $\log\left(x\right)+\log(x-2)=\log(3x)$ is not defined at x=0 henc only x=5 is the final answer.
