Challenge Problems
Push your limits with advanced challenges
A steel beam of length 4 m with a cross-sectional area of 0.01 m² is subjected to a uniform axial load of 2000 N. Calculate the stress, elongation of the beam, and the energy stored.
💡 Hint: Use Young's Modulus for steel, which is about 200 GPa.
Discuss the impact of increasing the length of a beam on the axial extensional energy given a constant load.
💡 Hint: Consider how the load affects stretching across more material.
