Challenge Problems
Push your limits with challenges.
Question 1
A steel wire has an initial diameter of 5 mm and is stretched resulting in a lateral strain of 0.01. What is the longitudinal strain if Poisson's ratio for this steel is 0.3?
💡 Hint: Rearranging the ratio will help solve for the longitudinal strain.
Question 2
If a cylindrical rubber rod can sustain a longitudinal strain of 10% before reaching its elastic limit while having a Poisson's ratio of 0.45, what is the expected lateral strain when stretched?
💡 Hint: Substitute known values into the formula.
