Question 1
What does Young's modulus measure?
- Stiffness of a material
- Shear resistance
- Lateral contraction
💡 Hint: Think about how different materials react to forces.
Question 2

Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical rod has a length of 2 m and a diameter of 0.05 m. If a tensile load of 2000 N is applied, calculate the elongation of the rod. Use E = 70 GPa.
💡 Hint: Use the formula ΔL = (σ*L)/(E) for elongation.
Question 2
Considering the relationship between E, G, and ν, if a material has E = 150 GPa and ν = 0.2, find the shear modulus G.
💡 Hint: Apply the relationship between Young's modulus, Poisson's ratio, and shear modulus.
