Challenge Problems
Push your limits with advanced challenges
A copper wire of length 5 m and cross-sectional area 3 × 10^-5 m² is stretched by a 100 N force. Calculate the elastic potential energy stored in the wire if Young's modulus for copper is 110 GPa.
💡 Hint: Make sure to calculate all steps carefully.
Discuss how the elastic potential energy concept is vital in designing suspension bridges, and calculate the work done in stretching the cables if a load of 50,000 N is applied.
💡 Hint: Consider how forces change during use in the real world.
