A strip ofmetal is originally 1.2m long. Itis stretched in three steps: first to a length of 1.6m, then to 2.2 m, and finally to

andreyandreev [35.5K]

Answer:

strains for the respective cases are

0.287

0.318

0.127

and for the entire process 0.733

Explanation:

The formula for the true strain is given as:

$\epsilon =\ln \frac{l}{l_{o}}$

Where

$\epsilon =$ True strain

l= length of the member after deformation

$l_{o} =$ original length of the member

<u>Now for the first case we have</u>

l= 1.6m

$l_{o} = 1.2m$

thus,

$\epsilon =\ln \frac{1.6}{1.2}$

$\epsilon =0.287$

<u>similarly for the second case we have</u>

l= 2.2m

$l_{o} = 1.6m$ (as the length is changing from 1.6m in this case)

thus,

$\epsilon =\ln \frac{2.2}{1.6}$

$\epsilon =0.318$

<u>Now for the third case</u>

l= 2.5m

$l_{o} = 2.2m$

thus,

$\epsilon =\ln \frac{2.5}{2.2}$

$\epsilon =0.127$

<u>Now the true strain for the entire process</u>

l=2.5m

$l_{o} = 1.2m$

thus,

$\epsilon =\ln \frac{2.5}{1.2}$

$\epsilon =0.733$

The connection is made using a bolt and nut and two washers. If the allowable bearing stress of the washers on the boards is (sb

Yuki888 [10]

Answer:

P = 0.490 kip

Explanation:

given data

allowable bearing stress = 2 ksi

allowable tensile stress = 18 ksi

diameter = 0.31 in

outer diameter = 0.75 in

inner diameter (hole) = 0.50 in

solution

we find here cross section area of shank that is express as

Area = $\frac{\pi }{4} \times d^2$ ..................1

area = $\frac{\pi }{4} \times 0.31^2$

area = 0.0754 in²

and

now we get here allowable load in bolt will be

$\sigma = \frac{P}{A}$ ...................2

P = $\sigma \times A$

P = 18 × 10³ × 0.0754

P = 1357.2 = 1.357 kip

and

now find here area of washer is

Area = $\frac{\pi }{4} \times (d^2-d1^2)$ .......................3

put here value

Area = $\frac{\pi }{4} \times (0.75^2-0.5^2)$

area = 0.2454 in²

so now we get here allowable load of washer will be

$\sigma = \frac{P}{Area}$ .....................4

P = 2 × 10³ × 0.245

P = 490 = 0.490 kip
