← ScienceIn elevator cables experiencing upward acceleration, which consequence results when the principle of equivalence applies?
A)Increased cable tension unexpectedly appears✓
B)Unexpected damping reduces cable oscillation
C)Harmonic resonance cancels weight increase
D)Shear stress remains unchanged overall
💡 Explanation
Increased tension unexpectedly appears because acceleration simulates a gravitational field. Therefore, the cable experiences a perceived increase in weight due to the principle of equivalence, rather than alternatives such as damping since tension is now a more salient issue.
