03.2: Lateral Strain

Question 1

What is Poisson’s Ratio?

Answer 1

Lateral Strain = Poisson’s Ratio × Axial Strain

Question 2

The ratio of
change in radius to the original radius

Answer 2

Lateral Strain/Transverse Strain

Question 3

The ratio of change
in length to the original length

Answer 3

Longitudinal Strain/Axial Strain

Question 4

The ratio of lateral strain to longitudinal strain

Answer 4

Poisson’s Ratio

Question 5

What is Axial Strain?

Answer 5

Deformation = Strain × Length

Question 6

What is Lateral Strain or Transverse Strain?

Answer 6

Lateral Strain = Axial Strain × Poisson’s Ratio

or

Change in Length (x) = Lateral Strain × Original Length

Question 7

What is Hooke’s Law?

Answer 7

Stress = Strain × Elasticity of Modulus

Question 8

What is Modulus of Rigidity?

Answer 8

Modulus of Elasticity = 2 × Modulus of Rigidity × (1 + Poisson’s Ratio)

where Modulus of Rigidity < Modulus of Elasticity

Question 9

What is Strain Energy?

Answer 9

2 × Strain Energy × Area × Elasticity of Modulus = (Applied Load)² × Length

Question 10

What is Bulk Modulus?

Answer 10

Elasticity of Modulus = 3 × Bulk Modulus × (1 + (2 × Poisson’s Ratio))

Question 11

What is Dilation?

Answer 11

Elasticity of Modulus × Dilation = –3 × (1 – (2 × Poisson’s Ratio)) × Applied Load

Question 12

What is Effective Modulus of Elasticity?

Answer 12

Elasticity of Modulus = Effective Modulus of Elasticity × (1 – (Poisson’s Ratio)²)

Question 13

What is Effective Value of Poisson’s Ratio?

Answer 13

Poisson’s Ratio = Effective Value of Poisson’s Ratio × (1 – Poisson’s Ratio)
