A material has a Poisson's ratio of 0.3. What is the ratio of lateral strain to longitudinal strain?
Step 1: Understand what Poisson's ratio is. It is a measure of how much a material deforms in the lateral direction when it is stretched or compressed in the longitudinal direction.
Step 2: Know the formula for Poisson's ratio (ν): ν = - (lateral strain) / (longitudinal strain).
Step 3: In this case, the Poisson's ratio is given as 0.3.
Step 4: This means that the negative ratio of lateral strain to longitudinal strain is 0.3.
Step 5: To find the ratio of lateral strain to longitudinal strain, we can write it as: lateral strain / longitudinal strain = -0.3.
Step 6: Therefore, the ratio of lateral strain to longitudinal strain is -0.3.
Poisson's Ratio – Poisson's ratio is a measure of the ratio of lateral strain to longitudinal strain in a material when it is deformed elastically.
