Challenge Problems

Push your limits with challenges.

Question 1

A cylindrical rod of material has a Young's modulus of 200 GPa and is subjected to a tensile stress that produces a strain of 0.005. Calculate the elongation of a 2 m long rod. Discuss also the implications of this elongation in real-world applications.

💡 Hint: Use the standard elongation formula and explore stress relationships.

Question 2

Consider the relationship between E, G, and ν. If the Young's modulus E is given, and you find Poisson’s ratio is 0.3, derive the shear modulus using the known relation.

💡 Hint: Employ relationships between moduli and confirm through calculations.
