Define longitudinal strain in your own words.
Think about stretching and how you measure it.
What does the symbol λ represent in strain calculations?
Consider the physical implications of stretch.
What is the formula for longitudinal strain?
Remember how strain relates to original and final dimensions.
True or False: Longitudinal strain can be negative.
Think about how materials respond to compressive forces.
A rod of length 1.5 m is stretched to a length of 1.505 m. What is the longitudinal strain?
Measure the change and express it in relation to the original length.
