Astrip 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 2.5 m. compute the true strain after each step, and the true strain for the entire process (i. e. for stretching from 1.2 m to 2.5 m).

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:

Where

True strain

l= length of the member after deformation

original length of the member

Now for the first case we have

l= 1.6m

thus,

similarly for the second case we have

l= 2.2m

  (as the length is changing from 1.6m in this case)

thus,

Now for the third case

l= 2.5m

thus,

Now the true strain for the entire process

l=2.5m

thus,

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.

answer:

i dont know the answer but good luck
