Question
A bar is compressed to half of its original length. The magnitude of true strain produced in the deformed bar is _________________ (correct to two decimal places).
Correct answer
0.69 to 0.7
Solution
True strain () is defined as:
where is the original length and is the final length.Given that the bar is compressed to half of its original length:
Substituting the values:
The magnitude of the true strain is .Correct to two decimal places, the magnitude is .
where is the original length and is the final length.Given that the bar is compressed to half of its original length:
Substituting the values:
The magnitude of the true strain is .Correct to two decimal places, the magnitude is .
