Challenge Problems
Push your limits with challenges.
Question 1
A steel beam with a Young's modulus of 210 GPa is 3 meters long and has a cross-sectional area of 100 cm². If a tensile force of 450 kN is applied, calculate the axial stress and the elongation of the beam.
💡 Hint: Break it down into steps: calculate stress first, then use the elongation formula.
Question 2
A cylindrical rod is 2 m long with a radius of 5 mm, subjected to an axial force of 6000 N. If the material has a Young's modulus of 70 GPa, calculate the rod's elongation.
💡 Hint: Remember to convert units where necessary!
