← ScienceWhich risk during a high-speed elevator cable snap increases, leveraging mechanicomechanical equivalence transformations?
A)Catastrophic shear stress propagation onset✓
B)Increased tensile strength of rope
C)Reduced gravitational potential energy
D)Decreased electromagnetic field exposure
💡 Explanation
Elevator freefalls convert potential energy into kinetic; therefore, the increased velocity causes larger inertial forces during a sudden stop. Sudden deceleration induces larger reactionary mechanical stress rather than tensile effects or energy dissipation, because of stress concentration.
