Challenge Problems
Push your limits with advanced challenges
A material exhibits a Young’s Modulus of 200 GPa and a Poisson’s Ratio of 0.25. Determine the Shear Modulus and Bulk Modulus.
💡 Hint: Make sure to apply your formulas correctly for each modulus.
A steel beam of length 2m and cross-sectional area 0.01m² is subjected to a tensile force of 40000N. Calculate the Young’s Modulus if the resulting elongation is 2mm.
💡 Hint: Ensure units are consistent while performing calculations.
